I bought GTA4 for the PC the other week, that required me to sign up for a Games For Windows Live account to track achievements etc (I believe the PC versions of Gears Of War and Assasins Creed also use it). Ill be buying a 360 next week, and the question I have is will I be able to use the same account for Xbox Live, or link the 2 in some way, or will I have to have seperate accounts?
