Just finished this last night:
Pretty awesome and the combat is fantastic and responsive and similar to God of War, but the pacing is a little off and it didn't feel as tightly knit as the first one, despite all the component parts being better and more realised. Weird.
Also, picked this up the other day:
And the new Infinity physics engine is equal part awesome and hilarious. Played a few games with a mate yesterday and we had great fun. Rosters are really new as well, with Manning on the Broncos team and Luck playing for the Colts. Wasn't expecting that.
Last of all, I've got this on the way:
Love MGS2 and 3 so excited to replay them, plus I've never played Peace Walker, so that'll fill in the story nicely before Ground Zeroes.
