I was thinking about this today, since I'm close to finishing the game I'm currently playing. I think this year will end up being 4 games for me, though they're JRPGs so it takes me a while longer (and I usually try to 100% games I like)
Finish can also just mean play until you're satisfied too. So maybe a better question is how many games do you usually play each year?
As far as online games go, I'm also playing Splatoon 3 and Overwatch 2
like a couple dozen I think, going by your definition. Though I caught roguelike brain a year or so ago, so maybe take that down to like, 15? If we're counting itch.io stuff it's probably a lot more.
