It's disturbing how much the "free world" has in common with the oppressive regime in China.
The US government sanctions murder, the UK government loves to spy on its citizens and the Australians love to ban "adult content" including games.

As for the Australians, I thought this was an interesting take on the lack of an 18+ category for games:
