Bayonetta (360 version) - 9/10
Better than Devil May Cry and God of War. The game is just plain fun: great fighting system, hot protagonist and other charming characters, over the top style and action, and upbeat music.
Red Dead Redemption - 8/10
Much better than GTA4 - riding horses >>>>>>> driving cars trying not to anger cops. There's more activities and little side quests to do in the world. Very likable protagonist. Dead Eye is pretty cool.
Can get a little repetitious riding around to every mission, but again, horse riding is much less annoying than driving cars around trying not to bump anything.
