Usually, when a game makes you choose between good and evil, the paths are so similar or uninspired that playing through a second time seems like a chore. [[xref:http://www.gamepro.com/games/ps3/134601/infamous/|inFamous|inFamous]] turned this gameplay element on its head with the Karma System, which actually changed the way you could unleash your electricity-based powers on Empire City. If you're a hero, crowds love you, but if you're a jerk to random bystanders, they'll actually pelt you with rocks or run in terror. Sucker Punch also nailed the exploration mechanics in inFamous, making simple things like getting from one end of town to another fluid and satisfying (as long as you didn't run into a chain link fence). Whether you play the game as a good guy or a total ass, inFamous is sandbox-style gameplay taken to near-perfection.
