It runs a lot better(for me) and we have access to all the maps. Other than that, nothing that I'm aware of. I'm a BF noob so there may be a ton of stuff I may have missed.
I haven't played in a week cause I'm alone. This is not a game to play team solo. Most of my friends bought MW3. They know how trashed the game is yet, they still fricken buy it. They arn't even playing on the dedicated servers. They are all wrapped up in the amature treadmill of IWnet . They are already complaining about lag and stuff in vent. I just bite my tongue.
I want to play with them but with a 60 FOV and that mwsatool(the thing were the host can kick you. I HATE THAT DAMN THING!!! ) I just can't bring myself to do it. IW and Activision said blank you PC gamers and yet they still buy it....in droves.
So now I sit here with my thumb up my ass because I refuse to buy that POS.
Edit: and no I don't have a life. I'm retired.
