Let's hope not PSP, X-Box, or PS3. Because Sonic Team would basically be destroying the whole "Don't remake it with just better graphics" thing. I would kill them if they turned NiGHTS into Sonic.
Reala the Nightmaren
NiGHTS Riders (sounds fun, but they would murder it in cold blood)
NiGHTS Golf (ye gods, this is in production)
NiGHTS Adventure 2
NiGHTS Advance 2 & 3
NiGHTS Adventure: DX: Director's Cut
NiGHTS Adventure 2: Battle
NiGHTS Shuffle (That sounds REALLY fun...)
NiGHTS and Reala (in the place of Sonic and Knuckles)
NiGHTS Drift 2
NiGHTS the Nightmaren 07'
haha, that would be awful.
I'm hoping they would released the original NiGHTS via virtual console or xbox live arcade. I wouldn't mind seeing NiGHTS on a portable. The Nintendo DS really suits NiGHTS.
I highly doubt that we would see NiGHTS sequel appear on the PSP, PS3, or xbox 360.
