I've seen some of the video of Titanfall and it does look good, not great not a lot better than Xbox 360 but as one of the first games for Xbox One it's not bad!
Sadly to enter this comp you have to buy Xbox Live, fine if you've got either a 360 or a One already, but if you've got a One why enter it? Guess ebay would be a good option:
