A good port, but overrated due to dreamcast hype and word of mouth from people that consider only graphics(and even then, the PC version can be prettier with HD texture mod).

Questionable visual changes like the overall brighter vibe, the completely different and more generic world map inspired by crash bandicoot(which imo kills a big part of the mysterious vibe that made rayman 2 so special in the first place) and also a few really dumb gameplay decisions like adding an extra enemy that sends bombs at the end of the already very long first level just to confuse the player or replacing the enemies with weaker ones in the already short and easy first sanctuary make it inferior to the PC and even N64 versions.

Plus I suspect there may be something wrong with the hitboxes in this port, I've replayed this game like twenty times and I never had much problem with the swamp level, but the time I played the dreamcast it somehow became the hardest level of the game.
