I personally think its quite funny how our government can't see that it is breeding pirates and thieves, by that i mean i am DEFINATELY going to get this game, i live in australia and if i cant get it by other means i will probably pirate it.
My point? the only reason i know how to pirate and where to get pirated games from is because of the stupid cencorship laws, a game comes out that i want im going to figure out how to get it, if we had an R rating it would never have given me a reason to search for illigal ways to attain the game in the first place and i still wouldnt know.
Dont get me wrong i have nothing against paying for games, and i would easily spend money on a game as much as i enjoyed as left for dead but im sure many people out there arent quite so happy to spend money on games and will just go on pirating.
Get an R rating, reduce the ammount of people that will try and beat the system and get the game anyway, you are losing tax and the developers are losing money.
