lol MW2 copy? seriously?
First off, The Battlefield series started out before the CoD series.
Secondly, what's in the demo that makes you guys think its a CoD rifopff? Either you're playing it wrong, or didn't give it much chance.
Tactical warfare with emphasize on Teamwork, HUGE maps, vehicles (Land, Air, Sea), completely destructible environment , etc...
Last time I checked, CoD didn't have those.
EDIT: I forgot to mention that BFBC2 isn't a "plug and play" type of game like MW2, it needs time to get into.
