The difference is pretty huge.
I still wish Ubisoft would drop Rayman and make a new IP. I love the graphics and gameplay, but I hate the characters and art-style so much.
Will still get it if no uplay.
Same as me. Don't know why, but I've always despised Rayman character design.
But then again, Origins is too much fun to play to toss aside it just because I can't figure out what fucking beast is that Rayman guy.
And it's unbelievable how much they succeeded in improving aesthetics in Legends over Origins.
Now if only Ancel would find the time to develop that fucking Beyond Good & Evil 2... :'(
