Hey man...playing in MyCareer earning 10, 20, 40 VC, if you're good enough, going to take ages. Playing all day is not even going to give you enough to increase your stats... I also play exhibition, blacktop to get VC...seems to get decent 150 to 250 VC per game...only if 2K server is consistent in giving those VC , sometimes I played blacktop and exhibition and I didn't get any VC although it says updating VC earned in 2k server. I bought the VC, but that's cause I have some credit in PSN wallet. I'm happy to play exhibition, blacktop etc to get VC, but if 2k server is buggy then it's just a waste of time.
well it's an option so use your common sence and use it also it is very cheap and does not waste time playing endless amount of games
