It may be wierd but I actually find the souls games relaxing to me, every time I get super stressed I just kill some hollows with an ultra greatsword and everything is good. What games help you relax?
I hear Tetris Effect is a particularly good version for this. Is that game worth it? Seems overpriced.Tetris, since it shuts out everything else and I'm focused just on the hypnotic effects of the game.
