I have mixed feelings on this... On the one hand, it's NiGHTS, one of those games I liked so much I recorded the soundtrack to it because the official one was insufficient. So, that's very exciting. The original NiGHTS was not about graphics (they were polygonally-blocky and in some respects just ugly), so the fact that it's on the graphically-weakest system is not an issue.
I'm concerned about the control scheme, mainly. Appearing on the Wii, this could be subtle, or it could require huge movement to achieve the desired results. This is probably the best game so far to encourage people to go crazy with Wii remote flailings. I did that with the original, and it was the 360-degree Sega gamepad that came with the game, not a motion-sensitive controller.
