KZ was extremely mediocre IMO.
I picked up a used copy at GS for I think it was less than $10, played it for about an hour with the idea in mind of learning the back story for the KZ universe in anticipation of KZ2, and was put off by the rail-like and uninspired design of the game.
I actually took the game back to GS since they have a one week policy on returns for old games and that is the first time I've ever done that. I didn't want it in my collection and have no intention of ever playing the game again.
Of course in all fairness, I didn't play the entire game, but... when finishing a game feels like more of a chore to play than entertainment, that's when it's time to put down the controller.
That being said, I do plan on picking up the PSP game before KZ2 comes out.
