Looking at those comments, I think they would have been yelling that no matter what won.
Black Ops? My favourite game is Mass Effect 2! How fucking stupid!
Mass Effect 2!? That's not my favourite game! Why didn't Mafia 2 Win!
Mafia 2!? Stupid GTA Clone! It should have been Red Dead Redemption!
Red Dead Redemption! LOL GTA WIV HORSES, It should be MY FAVOURITE GAME!
HAving said that, I'm going to chime in again that there are still a lot of great and original games this generation from many developers and publishers.
Off the top of my head, Zeno Clash is one of the most unique and intersting games I've ever played (I strongly advise you guys check it out), Brutal Legend was a brilliant game in concept, art and the unique gameplay mix of action and RTS, and if Bayonetta is original, then surely something like Bioshock is too!
