I'll keep the games if I have enough memory. I love to keep them as good memories. Just seeing the game icon makes me smile. It's always so hard to delete games I've already played because my memory is full.
I save all the games I like (I have external drives for that). I'm old enough to have seen a lot of old games and file sharing pages disappear forever, so I'm not taking any chances lol
I delete them but will try to memorize all the ones i've played and make a list so I can go back easier and replay if I want to. That and I like to give my friends my recs so it's just easier that way!
if it was a good one/memorable i will keep it, or atleast my saves. Otherwise i do delete atleast some of them, especially if it takes up relatively large space
Sometimes I replay those games while on call with some friends and let them make the choices on their own, it's pretty fun especially when they have absolutely no idea about the story or the characters lol. But usually I uninstall them and replay them again after like a year.
I have a 2TB portable drive that I keep my games in. Just in case they get deleted or become inaccessible. I also record all the games I have on Notion, so I know what I have archived.
My computer is pretty old and doesn't have very high specs, so sometimes I have to uninstall some games
Or I'll just focus on finishing one game at a time and keep the save data backed up somewhere.
Sometimes I want to delete games to free up storage space, but I try not to delete them as much as possible. Games I really love, I absolutely don't plan on deleting and will keep carefully saved.
Have to delete them because of the storage, as long as there are real game card or online server to download it again, but some of the games will be kept (the real loving ones) because it takes time to download (especially for games on NS).
