How much it did on ps ?Did it beat Nba, Fifa and GTAV on PSN ?Yeh, no.
Actually it was number one in steam for a while shortly after launch.
And that was when it was still broken as fuck. It did exceptionally well on Steam. Considering the quality of the game there's no reason why it shouldn't be number one or much closer.
Gta online very popular on Xbox and Nier is ahead GTAV there.
