Alright smart arse, allow me to narrow it down for you:
'I have no idea, I don't buy Rockstar games anymore'
If you don't buy them then how are you going to know what the social club community is like? You are not because funnily enough ROCKSTAR social club is only available on games made by ROCKSTAR. Ergo, if you do not buy games made by ROCKSTAR then you wont be using ROCKSTAR social club will you?
Better luck next time
I have no idea whether the serials from one GWFL 2.0 game work when registering another, moron. Learn to read.
I'm well aquaimted with the Social Club, like I said I have Max Payne 3 and have been playing it for quite a while (the multiplayer that is). I don't see any difference between it and GFWL, besides the aforementioned one which I'm not sure of yet, since I WON'T buy Rockstar games anymore so I WON'T be able to try and register an older game with a newer serial from another game.
Clear enough for you? Idiot.
Well next time say what you mean, saying I don't buy Rockstar games anymore suggests that you wouldn't have any of Rockstars recent release for example, i don't know... Max Payne 3 shall we say?
Whatever, you get the point.
