Like, games that you have played through multiple times, but you still like to replay them from time to time because you can just relax and have a good time without too much hassle.
For me some are Dark Souls 1&2 and Borderlands 1, I can play them without too much thoughts about what I’m doing, but still be focused enough so no bad thoughts appear.
DS1&2 are pretty relaxing ones you have like 2 playthroughs. Especially DS1, it’s a really short game. :D I’d love to check out Persona, but I have to start with the first game. Same for me in music, I’d have to start with the first album, I’m probably just a weirdo. :D
