Three things:
One, this isn't the actual game, it's a 'copied' version that isn't the same. So by the law, this game has to be rated by the correct governing body and given an appropriate rating based on THIS game, not THAT one.
Secondly, the "Teen" rating only applies in North America. There are totally and completely different rating systems in other countries where the American Teen rating wouldn't mean
shit.
Slap an Adults Only rating on it, and kids and teenagers (like me!

) from countries other than the US are still perfectly fine to view/play it, because they are still in their own country, sitting in their own houses, where that AO rating wouldn't mean fuck-all.
Three: SF? Teen rating? Piss off! I've been playing SF since I was 7, for fucks sake. Bollocks to "Teens Only". ^_^
