"What's your favorite game to play when you're feeling stressed? #gaming #stressrelief"
Animal Crossing. It's cute, and you kinda zen out taking care of your town/island (depending on version)
My "comfort" games are Fable 2 and 3, though. I end up going back every year or two. Because I can.
I don't have a game for stress relief.
Any game that has me invested is a stress reliever because it distracts me from the stress.
I have played a lot of Project Zomboid, over 3k hours. You have plenty to do but if you want to hide out in a cabin in the wilderness and listen to the birds, you can do that too. It's a great game for its ambience.
