Battlefield Bad Company 2 is actually pretty damn good. I picked it up cheap the other day and finished the campaign and it was pretty fun and action packed.
Haven't tried the online, kind of doubt I'll really like that part of the game, but the campaign was sick and they fixed a lot of issues I had with the first Bad Company game. For one thing, it has regeneration health instead of health packs or whatever, it also looks pretty solid, except the cut scenes look weird to me for some reason.
Anyone, I'd advise anyone looking for a game as a change of pace to check it out. Its like $8 used at Gamestop.
