One of the Playstation Greats.
It's a 3-D world, unlike the first. There are just so many differences between the two games, that the only similarity is that it's about Rayman. This game improved upon your punching abilities, allowing you to throw orbs instead of your fists, and later on charge those orbs into powerful blasts. This one also had the concept of as you progress, you gain more abilities, such has powering up your fist - orbs, the ability to fly and not just glide, to grab onto "lums" or those hoops in the air. The music is great, and the graphics are spectacular for its time, and the gameplay is very interactive and "actiony."
I highly recommend this game, for it is one of the Playstation greats.
