Sometimes, through no fault of their own, rival video game developers independently stumble into the same idea. On this week's episode of Power Button, we look back at games that competed based on similar concepts: Infamous versus Prototype, Split/Second versus Blur, and so on. We also look at smash hit games like Street Fighter II and Super Mario Kart and inspired a glut of also-ran imitations. It's an hour of great minds thinking alike or following the leader. By the way, why not check out Blake's Extra Life charity goal and see if you can help him out?
