I don't want to turn this into an argument at all, but after hearing that you didn't experience some of the most glaring issues (issues that large groups of people complained about) in MW2, I can't help but take everything you say about this game with a HUGE grain of salt.
Also, a bit hard to tell what issues the game might potentially have since it just came out. Dunno, don't really want to discuss it at length or anything cause I'm still not going to buy it. Just got Dark Souls, Skyrim coming out, playing BF3 too. Definitely isn't a game on my agenda.
