I try to play Metal Gear Solid 1-3 every year (and if I can't make all of them, at LEAST 3. It's just peak in the purest sense of the word), as well as the OG FF7.
There are a lot of like, 'faster' games I replay every year; the Mega Man X series, Spider-Man: Shattered Dimensions, various fighting games, but those don't feel like they take up enough time to be considered true replays haha.
