I meant the class updates and patches, but yes, had Valve not taken the time to choose the right style for their game we would have had an ultra-realistic team-based war game with RTS elements and graphics mostly made up of different shades of brown.

Also, GFWL is Games For Windows Live, the pathetic excuse Microsoft have for a multiplayer connection system. It's mainly what's responsible for the lag, matchmaking system, crappy marketplace thing, and so on.
