It's definitely the PS2 port. I've only played that on emulator, but the movement always felt off a little on PS2. Here, everything feels tight and fluid. The graphics are in line with the PS2 port, really smooth and geometric, and the colors really pop. The interview with Iizuka is terrible. No Sonic into dreams. Overall though, any NiGHTS is better than no NiGHTS, and playing this in Saturn mode (and the PS2 mode) has been a wonderful experience. It's almost exactly as I expected it'd be, which is high praise for SEGA in 2012.
