Ask ten people why they play video games and you'll get twenty different answers. Some will say they like taking out their anger on a military battlefield, shooting up friends and enemies for better ranks on a virtual scorecard. Others might want to go on surreal, dreamy adventures through deserts and mountains and rivers of fire. At least one or two people will say they just like to have fun.
But one of the more interesting answers is one that fewer people would like to admit: Video games are an escape. They let us forget about our troubles and inhabit other peoples' brains and bodies. The problems in video games always have quantifiable, achievable solutions. Where life is messy, video games are neat.
Maybe that's why everybody loves Persona 4.
