play the helicopter level (Jacky\'s), particularly with Lei Fei and Lau Chan and you will notice big discrepancies in the lighting, shimmering, flow of characters clothing, etc. PS2 Hardware could never recreate a game which uses NAOMI 2 to it\'s fullest, tons of texture memory, 6 (I think) light sources, etc. all at 10 million polys fully lit and textured! I say PS2 did a pretty damn good job doing it, though.
