Ok I am going to buy a new xbox slim. I will most likely only play gta4 and cod mw2 and forza 3. All on xbox live. Will the 4gb be enough??? Tight on money now I thought it looked like a good deal. I won't be installing the games to the device. Just game saves,xbox live, Maybe some music. But just playing from the disk. Would I be alright with the 4gb and getting a flash drive later if needed?? Would appreciate feedback!!
