Mirror's Edge, most definitely. I lvoed it for not only its different approach to first-person games, but also because it was diffent in everything from its colours to its cut-scenes.
I actually find it surprising that Yahtzee didn't like it. He complains about games with "gun-metal grey and dogshit brown" as their palette and the lack of originality in gaming, then EA brings out ME, completely different, and he kills it off. I find it really odd.
I think most of the complaints came down to people either not understanding the story becase it wasn't handed out on a platter for them, instead they actually had to THINK to get it; or people not being good at the game and complaining it was too hard.
Sorry, rant's over
