The first 2D game was great. Classic
Rayman 2 was the best ever. The plot, characters and levels were pretty good
Rayman 3 oh well. Worst than 2 but still good
Rayman M was based on R2 and it was only a multiplayer, good enjoyable game.
I haven't play Raving Rabits yet but I'm not interested. I saw almost everything about this game and... I don't the idea of rabits.
