Maybe there's a new character that looks like a Kangaroo or a Crocodile that gets beat by virtually all the other characters? They should just smooth things over by designing a rugged, outdoors-man type that responds to fighting characters with blade items with "That's not a knife, this is a knife" before hauling out a massive sword.
You can get around this by getting an U.S. XBOX and hack it to play burned games. Then download the U.S. version of the game online and burn it to play. You'll need to get an old non-slim xbox, though. The slims don't have a reliable hack yet I don't think.
If you don't want to break the law, you could just wait it out. Atkinson is gone and the tide of opinion appears to be turning in favour of a R18+ classification. I predict we'll get one within the next year or two (I know that's probably little comfort to you). Unfortunately, even if that happens current RC games may not get reclassified.
