Hey All, Really enjoying steam, I just wanted to ask, I was thinking about buying this game it looks pretty good! and since I lost my xbox 360 i've been missing online shooters, just two questions, since windows users and mac users can seemingly play this online together, is there many people still playing this game? is it popular? I'd hate to buy it and find no one really plays it online, and also how does it perform on the 330m? Thanks, Regards, John ps. tried to post on the actual steam forums but they have some kind of clearing policy before you post your account must be manually approved which i think is silly, but hey.
