I have NiGHTS and Christmas NiGHTS in my lurvly Saturn crate. Is Christmas NiGHTS in the new Wii version? Also, here's a little tidbit, the Saturn was actually a Dual core machine. After seeing Sonys PS presentation the CEO of Sega storms into the Saturn R&D and basically demands the team commit Hari Kiri for allowing the newcomer to kick their asses. Instead the team shoehorned in the second processor to aid 3D calculations on top of the dedicated 2D architecture, which led to the first crazy Dual Core machine. Its an oversimplication, but essentially this Dual core system is what everyone couldn't get their heads around programming for. Makes you wonder what a Coder today could do with it. Edit And each individual Saturn CPU was actually slower (2x 28 MHz) than the PS1's single core (running at 33 MHz). But I think there were bottlenecks for calculations/ram/something or other.
More likely that people wanting to get rid of it are rare. I say that because I remember when stores in my area had loads of the game. It came in a cardboard sleeve and stores were practically giving it away, and they still couldn't unload the things. In particular, I'd guess that in North America, where Saturn's popularity was at its lowest, anyone who still has a Saturn and a copy of Christmas NiGHTS probably has both of them on purpose. Dunno what the situation with it was in Europe, though I'm given to understand that the Saturn did a bit better there.
Thats the copy I have, on SSM, Sega Saturn Magazine! I hear that the SSM Panzer Dragoon Saga disc 1 giveaway goes for a fair amount as well.
