What the hell are all you waiting for? This is a really good game! It obviously caters to adults, but I know a lot of people that have bitched and moaned that there aren't enough games like this on the DS. This is why.
It's actually amazing looking in action and a lot of the screenshots do not do it it's proper justice. It has great use of the stylus, a feature that seems tacked on in most of the DS games that I have played.
