Ever since I was a kid, video games have been a great stress reliever for me. I usually like to played games that I've played before in the past like Super Smash Brothers (64 and Melee), Pokemon Blue, Mario Sunshine, any Kirby game I've owned, and Pulseman. I haven't thought much about why that is, but I think it's because playing a game that I'm familiar with is less stressful because knowing what's going to happen gives me a sense of order.
