I’m assuming there’d be no online multilayer or modding, as they’d be outside the realm of the game - it’s content made by other people (and it’s more interesting if you exclude them anyway), and I’m assuming there’d be no more updates (so only current or previous patches)

So we’d be looking for replayable single player games

1. Minecraft. If that’s not on your list then you’re joking
2. Terraria. Sandbox like minecraft, but the more legacy-focused scope of the game would be a nice change
3. Factorio. This game is called cracktorio for a reason
4. Monster Hunter world. Very replayable when you want to hit big monsters with big swords
5. Maimai. Bet you didn’t expect a rhythm game to be here, bitch! With all other video games gone, I’d finally be able to play maimai locally, instead of only in the city on the occasional day off. Yes, this list is just a place holder for the real number 1
