I wanted to give my girlfriend a gift and buy her Diablo 3. Since it is currently only possible to order online, I wanted to buy her a key from MMOGA, but I'm not familiar with Playstation and the platform only says Battle.net and not PS4. Can she still activate the key on her PS4?
No.
Battle.net is only pc
Okay, thanks for the quick reply. I'll just order it like that.
