Call of Duty World at War

Why do I play this game at all? I am so terrible at it yet cannot seem to stay away for very long. It reminds me daily of what my current physical condition has sunk to but for some strange stupid reason I come back again and again to desperately attempt to rank up. The previous version of the game (Call of Duty 4 Modern Combat) was tough in its own way but there were times when I could compete but when they went back to the WW2 weaponry I have just lost it.

New maps were released yesterday and I still am looking for my first successful game on any of the three. Even the new zombie map has frozen my out twice now - although both times the problem was hardware, not humanware.
