It's brilliant. I like the ultra violent direction the Wii has taken recently (see also The House of the Dead: Overkill and Dead Rising). Fuck being a "family console".
I think my favourite bit thus far has been using a massive baseball bat to smash people into an even more massive dartboard. Or chucking a flaming bin over someone's head and then launching them into an electric fence. Very wholesome.
So, anyone else have/played it?
