DON'T BUY THIS NOW!!!
Since the Gamespy servers which ran the SocialClub were shut down, GTA IV doesn't work, but instead of it being either fixed or taken off the store, it remains. And SecuROM - As you cannot connect to the socialclub, doesn't let the game start. This means that you cannot play the game. I have tryed all kinds of fixes but none work for me, it can someone else but not some, it isn't worth the risk at the price. I cannot wait for the Steam returns policy that has been rumored to be implemented because I would return the ♥♥♥♥ out of this. Which is a crying shame because I played this game on console on release and it was perfect and I wanted a similar experience on PC but to no avail.
♥♥♥♥ you SecuROM, ♥♥♥♥ you GFWL and most of all, ♥♥♥♥ you Steam for keeping a possibly faulty product on the store!
