It's my favorite new IP this gen (Assassin's being a close second). After playing all three, I can't pick which one i liked the best....or second best; i can't put an order on them at all. I thought they were all great and I really liked the characters (especially the sense of camaraderie i felt among them) and lore of the series.
I dislike third person shooters, so by reference, I dislike Gears. --- "In peace, vigilance. In war, victory. In death, sacrifice." ~ The Grey Wardens http://www.trueachievements.com/mygames.aspx?gamerid=71900
