Okay, this is going to be a good one, I know it! What do you think is the best looking video game from last generation? There are no rules for this: it can be a technically gorgeous game like Uncharted 2, or it can be a game with great art direction like... say Super Mario Galaxy. What's your choice?
It's a tricky one. I'm tempted to say Rayman Legends on the Xbox 360, but I don't know if that counts since it was released on next gen platforms. I also thought Super Mario Galaxy was gorgeous -- the Uncharted series too.
Gears of War was the first game that made me go... wow on the Xbox 360. Actually, Fight Night Round 3 might have been the first.
Man, this is tough. What's your choice?
