I did enjoy KZ2, not having played the first at all, & whilst not the greatest FPS by a long way there were enough satisfying elements - that being the Helghast were easy enough to dislike and pop a cap into.
I would have reservations if the wand thing was the only option re: gameplay. I'm not even sure what it is, but have never enjoyed, thus far, any of the motion sensor side of things that I have come across.
The 3-D thing does sound a little interesting - is this likely to come in a firmware patch upgrade - man, I hope so. I am kind-of stuck with my Phat PS3 'for financial reasons' and couldn't go for a new console, as I'm sure is the case for many people.
I await eagerly the release of KZ3 or any more than half-decent FPS.
