My GF and I just started playing this past weekend. All I can say is WOW, what a polished game. It's kick ass awesome and so much better then what I was expecting.
I haven't seen a game look this good in a long time.
The only negative comment my gf has about the game is that there is too much gun play in this game compared to the previous Tomb Raiders.
Anyways, I'd give is a 10/10 GOTY myself!
