Social Anxiety Survival Horror. You're a guy at a friend's party trying to avoid conversations while putting in an appearance with your friend so they know you were here. You can deflect conversations with small talk you pick up by eavesdropping, but it won't work on drunk people, so you also need to run and hide. Your ex-partner eventually shows up and is hunting you down to have a frank conversation about your relationship, which is instant game over.

100% science based dragon MMO

A driving (either racing or GTA-style) game that generates the roads from real-world geospatial data/street view imagery similar to how Microsoft Flight Simulator does.

NOTE: Someone probably has developed it, but I’m too poor to buy a decent computer.

I’ve been wanting the shittiest, most grindy military logistics game possible for a bit now. Like, “oh you didn’t upgrade your Sock factory? Fuck you now your platoon has trench foot” type Grindy.

I want to feel pain

SimEarth remake with a proper geologic and climate model.

All the newer games in that mode feel like they’re all about growing the predefined lifeforms.

SimEarth was more about making the planet to support the lifeforms.

An urbanism focussed city builder where you start with an existing city in the current car-centric style, possibly including a couple of dozen kilometers around the city so rural problems are included as well and have to transform it, with realistic building project times, into one that is more walkable, has safe bike paths, good public transport,...

In particular I would also like it to take verticality in to account both for transport (people and bikes and trains have a harder time going up and down than cars, boats need locks,...) and for buildings (stores at the bottom of a building, residential above,...) and that accounts for the huge amounts of space car-centric cities waste on parking as well as the ongoing infrastructure costs for maintenance and replacements of all that infrastructure in sprawling cities.

Basically "Not Just Bikes" the game.

Mirror’s Edge-style gameplay (specifically first person) for experiencing Spider-man’s first few weeks of having powers, including the time prior to having built the web-shooters. I have wanted this ever since the teaser trailer for the first Andrew Garfield movie.

I probably wouldn't want this game to actually exist, but it's been stuck in my head for years so here goes. I described this one a while ago. A friend of mine was on mushrooms once and described a first person WW1 game where you're an Austro-Hungarian courier running across battlefields. There would be parkour, time management, stealth, stuff like that. Sneaking through trenches and whatever. At first the missions go ok, easy enough. But then you're given more complex missions that waste your time, or are foolishly planned.

Your character begins mumbling under their breath about how the generals are doing everything wrong, the war is lost. Your character becomes more deranged as the missions become more fruitless. Eventually your guy will start screaming deranged conspiracies and wild racist shit. There would be a mechanic where you start to need amphetamines to function.

Then in the last mission you catch sight of your reflection in a puddle and you've been playing as Hitler this whole time.

Battlefield: Titanfall

Factorio-like game where you focus on sustainability rather than being the bad guy in an alien landscape. Need wood? Better replant or there won't be anything for higher levels of the game. Need metal? You can get it, but only in a few places and then you need to think about recycling what you have.

A Rockstar Open World Pirate game.

Black Flag was getting there, it had good vibes, but unfortunately they had to make it an Assassins Creed game and Ubisoft doesn't know how to do it right anyways. Rockstar does.

A spaceship captain game with an AI crew that follows your orders, and is focused on problem solving and exploration rather than combat and resource gathering. Kind of like ongoing episodes of star trek, but in game form.

I want a game that is a standard sci fi/fantasy RPG, except the main characters each suffer from a mental health condition that affects their gameplay (and of course the story).

My brother (now deceased) had both schizophrenia and numerous personalities. He had visual and auditory hallucinations thanks to the schizophrenia. On top of that, in my last conversation with him, he mentioned that all his personalities ‘shared information’ except for one that was in denial. Because of that, when a different personality took over after that one, he would have no idea what happened during the time that denial personality was in control. Sadly, my brother passed after he had stopped taking medications for a week and decided to use computer duster (something he had finally got clean of) to sleep and never woke up.

Now, imagine that in a high sci fi or fantasy RPG. You might begin fighting and wasting energy on enemies who aren’t actually there, but you think they are. You can go into battle and no other party members will help because, as you find out after, those enemies weren’t really there. Maybe you become weak because of a would and have to get through a dangerous area to get to a hospital. There you find you never had an injury, it was a hallucination (based on a 911 call my brother made thinking he had slit his throat when he had not). Maybe you go to learn some key information from a character who then dies dies suddenly. However, you don’t remember any of it.

Most important though, in the end, you are still the hero and still save the day. The idea being that yes people with these mental health challenges struggle, but they aren’t monsters. My brother was one of the kindest people I know and loved to help people. A game like that, if done right, could help players understand what these conditions are actually like (not hollywoods bs) and show that they can still be heroes. I think that would be cool

A game similar to the Expanse and Firefly. A space exploration, trading and combat game where you fly around a single solar system in a small ship and can also land on planets (please not procedurally generated though. Just make fewer places you can visit, but design them).
Oh, and with realistic Newtonian physics. Even if that means combat will be largely about who can fire the most missiles. But it would also mean you can avoid enemies altogether by planning the right planetary slingshot, millions of miles before you'd meet them.

Outer Wilds comes close, but I'd love something more gritty, realistic and on a bigger scale.

Hollow Knight Silksong :(

First person city planner, probably in vr where you can plan something out and then see your city grow as you walk around it

A game where you play a reporter in a pre-internet open world, digging through meetings, documents, connections and surveillance to get information to create stories.
You could have relationships with people too, and test them. Go with a private story on someone that will get big views and make the rent but piss them off, or keep it private and maintain your relationship to access their connections to try for a bigger story.

Planetside 2, but in Warhammer 40k. I want to be an ork running around krumpin gits with a hundred other boyz, smashin up some humie tinboyz or them big bug wotsits

Bonus points if you can be a psyker and blow up your whole squad

I have this concept for a VR team battle game where you have to learn to actually cast spells through complex real time action. Like a mix of moving your hands in patterns and adding elements via hot bar in sequence and saying words via headphone. 1 on 1 or team vs team strategy game where complexity makes stronger team spells and counters. You could have casters who specialize in defense, offense, healers, traps and counters and how you build your team makes for strengths and weaknesses.

I have a horror game concept, based around the old days, back when used game stores actually were a good deal instead of just a price gouging den of collectors. Back when buying a copy of a game pre-owned meant that you got the save files of the old user with it.

So this is a harvest moon type, there is already a file here, the game yells at you if you try to delete it, you get characters telling you that you can't hide from what you have done. And when you play the game everyone is pissed at you, the world is in ruins, and making any real progress is next to impossible due to the horrible state the world's in and no one wanting to help you.

The object of the game would be to convince the people of the game world that you are not the original user, and that you want to set things right. And the new game plus would just be what the game is supposed to be like under normal conditions.

Admittedly I got the idea from hearing about a Harvest Moon friends of Mineral Town Creepypasta called The Goddess Has Not Forgiven You, which I can't actually find. But it was described by a harvest moon iceberg video. When I couldn't find the story that it was talking about, this was just kind of the idea I had for an indie game based off of it.

If you are an indie game designer who wants to do this, feel free to steal my idea, Just credit me for it and shoot me a copy of it if you can get a hold of me.

Honestly? Just a modern, improved take on an old WiiWare game called Final Fantasy Crystal Chronicles: My Life as a King.

There is nothing all that special about MLaaK on the surface: It's just a management sim with a Final Fantasy theme to it. Place buildings. Get soldiers (well, here 'adventurers'), send them out on missions. Get resources, invest them. In fact taken as a management sim it's very barebones and not that great?

The thing is, no video game ever has, in my eye, captured the feeling of being Fairytale Royalty. You have direct control over the king character (who is a 12 year old because. Final Fantasy) -- You walk around town. You want to see an overview of incomes and expenses? Go talk to your assistant and she'll give you a report. Want something built? Point to the plot and ring the chime to call a servant and say 'Magic college here'. Sending adventurers on their quests involves directly talking to them, and you can read their mood on how they react to the assignment, with motivated adventurers doing better. And when they return wounded you can visit them in the hospital for a boost to their morale and your popularity.

Also the higher the happiness level in the kingdom, the more citizens choose to stop and salute you, and the later you can wander around your town without your servants going "you're underaged and royal and it's dangerous at night, back to the castle now", because your subjects like you.

Idk, these small touches made the game feel very special for me back then, I've been chasing that high since. Shout out to Fable 3 for the variety of nice royalish clothes your character could try on, but no shout outs to it for anything else.

I want a vampire-survivors style game that integrates with my music streaming and the enemies/weapons sync to the music I’m playing.

VR tourism. Or even better: VR historical tourism!!!

No points, no battles, no level ups, no upgrades. Just exploring faraway or historical places.

A metal gear type game where the AI is trained on how all players play worldwide and it adapts and evolves over time in how it stations and uses its soldiers against you and for patrols. Every time you go back to play, the layouts and movements and gear and reactions of enemy AI differ.

Assassin's Creed Black Flag (aka AC: The Pirate Simulator) meets Sid Meiers Pirates! Live The Life.

Basically I want a giant open world with dozens of cities and even more small villages, modernish graphics, and be a pirate. And be able to lead a fleet. And swap ships.

I'm gonna be honest, due to my niche game preferences, if they could add in ability to upgrade and customize every ship with tons of options, including crazy ass "I zip tied a rocket motor to a group of hot wheels cars to see if I could skate" type things. "I replaced one mast with a trebuchet, and because I like to tempt death it also launches flaming oil soaked things" energy.

Maybe toss in a ship editor like starfield had, but with sloops and galleons and shit. Things like fake guns could add to intimidation factor, and while fake guns don't shoot, they need only good from afar. By the end of the game, hopefully your branding will allow you to win some fights before taking a shot.

And because I like games like Sim city/ cities skylines, building and management games and the like, I'd love if that could somehow be incorporated into things. Both on the ships themselves, and as your "pirate fortress" home base. And I'd want to be able to set up multiple bases, all working together.

All of the addons being an option but not required to finish since having to micromanage the happiness of Pegleg Dave because he ate in the dark without a table again would get old quick.

The downside is, because all these elements don't really mesh all that smoothly in a game setting, I don't even think it's possible to make a good game like that.

Basically I want to be a pirate king in a modern game, and actually feel like a king. In both ability to command what is essentially a rogue nation, and the mild headache that comes with managing it.

Mario Kart Maker, like Super Mario Maker but for Mario Kart tracks.

A co-op game set in a open/sandbox fantasy world that is truly alive, driven by AI. You can do as you wish, join a Kingdom as a soldier for example, set up a village somewhere maybe. Become a trader. Hunter. Whatever you want. The ultimate open survival game I guess.

But the key part is behind the scenes an AI will change the story of the world as time passes. Perhap on the other side of the continent a war wages between 2 factions that threatens to pull the whole region into termoil. Maybe you'll hear about it from a passing traveller. Maybe you won't hear about it at all and the next time you go travelling far and wide you realise a new Empire is rising.

Perhaps the AI decides to slowly bring about the collapse of society through climate change. Perhaps you become embroiled in a plot to assinate a King. The AI decides all the variables, you can only react to them, maybe you can try and change the story with your actions.

One day you are out hunting and you see in the distance an army marching to war. Maybe you decide to catch up and join the army. Or maybe you'll hide and hope that wherever that army is going, it won't come to your neck of the woods.

The AI continuously evolves the world around you to keep things interesting. Every game will be completely different.

It'll probably never get made, it is massive in scope.

Honey I Shrunk The Kids : The Video Game.

An open world game where you can explore and interact with the world in a large (2 houses and backyards?) map.

I want to be able to build a cabin in the woods, hunt and grow food, seasons the lot WITHOUT ZOMBIES ATTACKING ME

A good community-focused Rocket League clone. Ever since RL was bought out by Epic and it went F2P, the game has felt more and more soulless, and the community interactions have been super tonedeaf. As a small company, Psyonix gave out cool stuff like white hats for those who found bugs and custom titles for people who found their significant other via the game. It sucks that the best content in the game came the summer before and the summer right after Epic bought it. Since the game went free to play, though, it seemed like RL was just another accessory for Fortnite to grow.

Tl;dr: RL was freaking amazing when the devs were allowed to care about the community. Now, it's slowly losing the stuff that made it so special.

Portal 3. Come on, Valve! Don't you want my money?

An extremely violent racing game where the car damage looks like human gore

An open world Shadowrun game. I imagine it like a cross between Skyrim and GTA.

How about something like Overwatch 2, but 6v6, and no battle pass. Maybe it doles out rewards like skins and sprays and stuff for playing? Just spitballin' here.

Heck, add an annual subscription to pay the devs, but don't go all in with the overpriced cosmetics...

A game where you play a spider in a variety of environments (forest, city park, front porch, basement, etc) where you control each leg with a different keyboard key, maybe spacebar to jump, hold a back leg to access your web, etc. you have limited energy to move/create web, and you need to build webs and traps to catch bugs.

Skyrim but i dont have to manage any inventory or use any menu ever including to use potions food and spells and also the cities are huge

Any type of game (sandbox, RTS, etc) where the landscape changes dynamically.

All games are either player vs player or player vs mobs or player vs game-mechanics-that-affect-your-stats. But I have never played a game where I have to consider a river overflowing and destroying a village, or an avalanche, or earthquakes.

Even when there are environmental hazards, the base map never changes. Rivers never change their course, islands don't appear or disappear, oceans don't dry up, dams don't burst, quarries aren't excavated.

The world and nature are always dead and static.

Edit:

Actually, Dwarf Fortress does tick those boxes quite often.
