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?
You play however is the most fun to you! Gaming can become so much more fun when you realize that different difficulty levels are there to serve you and your enjoyment of the game, not the other way around!
