I've no problem with GFWL. I was asking about it because I thought it was like Steam and was wondering if it was worth me just installing and having done with it. My problem is being made to jump through hoops to play a game. GTA4 asks for too much unneccessary data, so it doesn't get my money. From what I've gathered this expansion does too, so I'll not buy that either. If, in fact, it installs painlessly (or as painlessly as any other PC game) then I'll consider buying it.
What takes the piss even more is the fact Fallout 3 is available on steam, yet even if you have the steam version you are forced to use another piece of shitty microsoft software.
And Shada, for the DLC, to purchase it and play it (without moving the files around yourself) you are forced to use it.
