I've beaten it with all three characters.
Kurt was by far the hardest, which is odd because (A) I found Max to be the hardest on the Dreamcast and (B) I think Kurt got dumbed down a little because it seems they removed some of the orbs you have to snipe around Zizzy's brain.
Overall, the base game is still there so I still liked it, but because of those idiocies I wouldn't recommend this version to anyone (except maybe pansies whom I can easily imagine throwing their controllers). If you think you'd rather get this version because you have a PS2 but not a Dreamcast, then get a Dreamcast. They're maybe 25 bucks.
And no, I'm not making it Game of the Moment. I've already featured the superior Dreamcast version.
