(Saw this question asked on another popular link aggregation website and it got me thinking)
If you could play one game for the first time all over again, what would you choose? This might be because you want to do it all again, or because you don't think you got enough out of it the first time. It could be experiencing the game exactly as you were back then, or experiencing a game with what you know now.
For me, it's Legend of Zelda: A Link To The Past, experienced exactly as I was back in 1991.
Nothing comes close to how jaw-droppingly amazed I was by that opening sequence. The epic orchestral score, the cinematic rainstorm, creeping around in the dark... it was a generational leap above anything I'd played on 8-bit computers and consoles, and even the Megadrive. I'd love to play it again without thirty plus years of Nintendo/Zelda knowledge, or without knowing about the dark world.
Subnautica.
The first game to make me truly sad that I had finished it. Wow, what an experience!
I loved exploring and piecing together the story. I loved discovering new creatures and ecosystems. I loved finding strange things and figuring out what to do with them.
I've never played a game quite like it before or since. My god, it was really amazing. I beat it without needing a guide or walkthrough. It's great enough to the point where, if you are curious enough, you won't need one!
It's certainly a slower-paced game, as it's not all non-stop action, so it's not for everyone. But if you're a patient and curious person, this may be for you.
Maybe give outer wilds a try. Exploration and really unique level design.
