I had a play of the BFBC demo today and I gotta say its pretty sweet, and suprisingly seems to have a decent plot and pretty good writing to boot. I especially liked the music at the menu screen, the game has a sense of humour in a serious battle setting, it makes for interesting black humour.

As for the gameplay, its fairly reminiscent of COD4 but with vehicles and destructible evironments, its very fun and the netcode is sweet, I didnt experience lag once, and thats rare. The graphics are nice, especally the character models and textures, but it seems to be running at a lower rez, like COD4. I only played the PS3 version so I can't speak for the 360 version (My live account has expired and I haven't renewed it yet).

All in all it looks very promising and its a rare case of a demo making me want the full game, I'd suggest everyone who likes those kind of games should go check it out.
