Ask Lemmy

Mostly anything I play in VR. I have a basic sim rig I use for Euro Truck 2 and American Truck Simulators, and some DiRT Rally 2 ever so often. Outside of upgrading to a rig with hydraulics and a buttkicker, it's pretty immersive. For non-vehicular VR, I'm running around in Skyrim with a hefty modlist (1100 mods), and just the baseline mods like HIGGS, PLANCK, and the Community Shaders set of mods adds a huge amount of immersion with the ability to directly interact in the world.

Flat screen gaming, otoh, I would say Project Zomboid. Despite its simple appearance, the amount of mods available really amp up "realism", in that you can add so much living to the world. The lifestyle mod alone adds a bunch of Sims-like layers to the gameplay.

Wing Commander

I still have every single game in the franchise, bought them new as they came out over the years.

For single player fantasy, Outward is my favorite game to get immersed in. It has a bit of a steep learning curve, but the survival mechanics and lack of a leveling system really aid in the feeling that you're getting better at playing the game as your gear gets better. The combat encourages patience and preparation rather than jumping into the fray and swinging wildly. And the magic system, good lord. There are several vague categories, but the best way to describe it would be 'ritualistic.' There are spells with fairly benign effects on their own that, when used in conjunction with other spells or effects, produce deviating or beneficial results. And the NG+ mechanics are fair and balanced while offering a boost to follow-on playthroughs.

The most significant barrier to entry is the learning curve, mostly learning about combat, patience, and the stability system. But it's my personal favorite.

The Mass Effect Trilogy. Just can't stop playing that game haha
