Greatly disappointed with this game. At a certain point in the game it stops my Video card from working and shuts down my PC. On investigating in forums and internet it seems this is a common problem with the game, quite a sad reflection on Valve and Steam and I don't like the way Steam Hijacks all your legitimately purchased games and you can't play them if your not connected to a Steam account. I DON'T WANT TO PLAY MY GAMES IN MULTIPLAYER ON LINE!!!
