Finally found a copy in Canada! Easily one of the most fun game play experiences I've had in a while. A tad repetitive and lots of "press A"; but hot damn if it all doesn't melt away when you get to the next ranked assassin.

 

I am now about 25% through my second run through the game. The first time was incredibly fun, but I completely rushed through it. On my second run, I'm working on being a completist; i.e. finding all the Lovikov balls, getting all the weapons (which I've already done), learning all the techniques, etc.
My advice to those who haven't got it: Don't start on Easy (or rather, "Sweet") as it is really really easy.
