I guess they used the whole pirate theme for the reason for being really dark. As far as Rayman 1, the best version IMO was the Atari Jaguar version. The colors were more lush, and the music was way better than the PSOne and Sega Saturn versions. And the music when you met Ly, it was awesome in Rayman 1, the Jaguar version, I wish they used it in Rayman 2
