As mentioned in the post the tech behind Rayman Legends is beautiful and the results are inspirational. I have a real soft spot for this 2D styling from my own drawings to comics and such. While fully rendered 3D is cool, this 2D aesthetic is lovely and approachable. Here are 3 Rayman Legends videos, first the tech interview, then the launch trailer that shows how it all comes together and lastly a pretty nice 3D CGI promo video that shows off the different style.
While we are here, we should throw a few groovy concept art images on here, some environment/level concepts from Aymeric Kevin's blog.
