Xcom was great.
I didn't play anything I hated, or even disliked. I always try to find ways to enjoy the games I buy, and I always wait for the reviews. But... yeah, The Secret World had more, and longer, dull moments than I prefer. So that my pick.
Favourite game will have to be a toss-up between Torchlight 2 and X-Com.
I actually don't read reviews anymore. I buy games if they seem cool and/or interesting based on the limited coverage I consume.
I watch GB quick looks, I listen to a few podcasts, and I check metacritic out of curiosity from time to time.
Usually, I just buy what sounds interesting or games by developers with good track records.
I usually don't pay more than $40 for new games (deals are everywhere, even day one), so if I don't enjoy it, I can recoup at least $30 of the cost by dropping said game off at Best Buy.
The Bombcast steered me wrong on Fez and Bully, for example, but they also got me to hop on Asura's Wrath (which is BANANAS).
Anyhow, vibe has guided my buying decisions more than reviews lately, and I'm very happy for it.
