GTA IV Australian Edition
GTA IV for Australia Will be a bit different,Why?.
in Australia there not aloud to have games that are Rated Anywhere over MA15+, but Grand Theft Auto is R18 so Rockstar Games were forced to make an Australian Edition or it will not be aloud to be brought into Australia.
The Content that was taken out were Sexual Scenes,less Offensive Words,and some smaller things . it's really nothing to worry about as the Storyline is exactly the same and in the same city and places.
Well i hope that answered some of your questions.
You Americans are lucky they you don't have any of your GTA games edited... We have to suffer thanks to our ratings system.
