Oh this will be tough to narrow down... but starting off I am a die-hard FFX fan so that'll be 1. Next up I'll go with a series - Mass Effect (1-3), I love the world building, all the different characters, and Garrus is my husband. Next up probably the Souls series, DS1-3 was really core to what I played frequently and I'll still return every few years for another playthrough. Disco Elysium is another standout that is unforgettable and I will lament constantly that everything at the studio fell apart and burned. I'll use my last game for an obscure sleeper hit - Call of Cthulhu Dark Corners of the Earth. It's super buggy and old but since there's so few standout playable Lovecraft adventures it stands out for having a great atmosphere and interesting game mechanics. I might stream it for Halloween since I try to revisit it yearly.
