I am sad to tell you there aint no Grand Theft Auto for PC U_U
There won't be one.
Never, that's when
Rockstar said NO to PC.
releasing on the PC is orders of magnitudes more difficult then on consoles, because there is such a veriety of hardware and software that it will never work on all of them, i mean think if your game needs to support stuff like intel HD graphics cards or win/mac/linux on launch. it's the main reason game developers love consoles so much, if it works on their consoles at the office it will work on all consoles.
it will defenitly come to PC, but it will take time.
