Rob: I haven't heard anything about this. As PIAC said, GTA 3 had to be changed to suit the MA rating it received, because anything outside it is banned.
My guess is, at worst, that the developers will have to put in warnings at the loading screens. Nothing too drastic, enough to keep the politicians happy.
Street driving is a problem here - I live about 15km from the city, almost rural area, and its not uncommon to hear the drag cars go past at night. And with people driving from a younger age (16.5 is the earliest a person can drive alone) it is concerning. So either way, I'm happy. Brilliant game or fewer hoons. Doesn't matter to me...
I haven't heard boo about PGR2 yet. If its as addictive as PGR1, I'll be playing it a bit. *insert long drift here*
But the one gripe that I had is that the game wasn't all that fast. Compared to Burnout at least. But I guess it is a simulation racer and all.
