Being as this is the first game to be banned by the BBFC in 10 years (and that, Carmageddon, was overturned on appeal), I suspect two things; 1) this probably isn't an assault on freedom of expression, and 2) I really don't want to play this game.

Which isn't to say I'm not afraid of the precedent this sets, but I'm prepared to believe the BBFC when they say that this game was an exception.
