This model was a joke and I never understood why it exists. IIRC GT5 had the same issue, basically took the entire drive just to play it. I always laugh on the inside when I see someone buying it. I want to warn them about mandatory installs and HDD space but then I think it's none of my business if they wanna make a dumb purchase.
What's up with the irrelevant 360 shit that some of you couldn't help but bring into the thread? Yeah, it doesn't work on 4GB 360's, which Rockstar made people aware of from the start, since it was an issue from the start. Now it's an issue for the 12GB PS3, so they are letting people know. No need to arm yourselves.
