I was a bit too lazy to translate, but here's the info from the article:
- It was more accessible than R1 in terms of skill challenges but you needed to think more (as in puzzles?). A different concept.
- You had to free all your friends to complete the game.
- The robots come from space and want to turn the planet into a cold ball of metal.
- Rayman's island was rid of Mr Dark ( according to the article, it's an island, and Mr Dark is actually completely gone ).
- Rayman starts out with all his powers from the previous game but then discovers his multidirectional fist, platform fist (you can use your fist as a platform), surface breaking for more secret passages, and swimming. And that's not all.
- He starts using tools like a plunger vehicle, a hook, a laser pistol, and a "deviant", which is something used to be able to make your first rebound. And that's - again - not all.
- Rayman can go into the background as well, which we know.
- He has new friends who follow and help him.
- You were able to mount some animals in the game ( robot dinosaur! ).
... man I want this. It looks like Ancel copied some things from this in the R4 prototype - which got canned again, just like this R2 prototype. Damn.
I mean, plungers? RRR, anyone? The ability to use tools and mount animals? Uh... R4 prototype?
And some things got implemented in the final R2 as well. Freeing your friends (Ly, Globox), puzzles (sanctuaries!), rebounding "fist", friends who follow and help...
