I wanna say I absolutely love how Origins is a complete throwback to Rayman 1, even referencing Mr. Dark, but I'm upset that they threw out a lot of the story (namely Ales's backstory) last minute.
I'm really conflicted between art styles, I love them both in different ways for different reasons...
The music levels really make Legends, honestly, theyre so fun to play, plus the fact that they put in the Origins levels is awesome.
The new Lum mechanic is new and interesting, although it's really not as exciting or satisfying as collecting the King Lum in Origins...
on a similar note it's also more exciting to see Ales at the end of every level on Origins and watch his betrayal unfold sorry he's my faveI miss seeing the Nymphs in Legends, too...
Honestly though I still think Legends is more fun to play. I'm a huge Rayman fan (the franchise is my 3rd favorite gaming franchise, after Pokémon and Klonoa) and I think this game is the best the series has had. It's also the first main series Rayman game (I believe there was one racer/fighting spin off in this category) to let you play as a girl, and all the girls look bad ***, haha!
If I had the money I'd buy Origins a 3rd time, and Legends a 2nd time so I can play them both on my PS3 and take in the HD-est quality of them that I can!
