Comfort games?

With gaming often bringing me into a really depressive headspace sometimes with how the markets are developing, whats a game you can always go to and just be lost in, or just be happy with?

Personally i would go for advance wars 1 and 2 on the gba (there is no remake and never will be)

the artstyle, the music, the game-play is just simple, yet effective, a sublime experience of very fun times.

Whats yours?
