How can oblivion fita fuckin DVD then, n00b? Oblivion is bigger than GTA, n00b. Therefore GTAIV can fit on a DVD n00b, for the same reason it can be played on a 360, n00b.
To conclude: You ain't got a fuckin clue what you're on about.
LMAO!
If it does come out for PC it will be talked about months after the 360 and PS3 ones come out
