Yeah I think GFWL slows down the patching process tremendously. It completely makes makes useless steam's ability to patch quickly. I think other than the matchmaking system which is superior to steam's, I think it's a mistake. If only steam has a better peer to peer matchmaking system. I know left4dead was valve's first attempt at this. But hopefully they will make it's superior to gfwl's system and then there will be no reason to use gfwl in future games (other than getting kickback from microsoft for using it).
