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.
I’m perhaps the outlier in that I felt like San Andreas felt like they’d thrown shit at the wall to see what would stick. Most of the extra mechanics didn’t land for me at all and I was pleased to see them gone.
