i havent preordered it, nor really looked at anything about the game, literally I know nothing of it other than the title. I played the shit outta 1, even after 2 came out because with xbox connect you were able to play it online via system link.
2 was cool, had fun with it, and 3 was cool as well, played it for a couple months. But like everything it gets boring. same thing happened with me in call of duty, played the shit outta 4 and then never touched waw, or mw2.
I doubt ill pick it up, I am more of a fpfps guy, (fast paced). The first unreal championship on xbox I hit top 5 at one point and quake 4 was amazing, I was number 2 on the leaderboards and couldnt hit number one only because I started playing late and the number 1's points were a lot higher than mine and he was still playing non stop.
Another thing to note, People might seem to be good online, but there is a whole nother group who you wont really find inside of ranked matches. I played quake 4 like crazy, and someone noticed me, sent me an invite to a private match, the match was filled with people I have never seen, needless to say I got my ass handed to me. and for quite some time, I got better by playing them and they taught me some new tricks, but it goes to show theres always someone better out there. This same clan did the same with CoD and GoW, played private player matches with some elite kids.
