Graphics: Of course, nothing to do with next-gen that you should not expect, however. Compared to Super Mario and other games in the Jump-n-Run Genre of this game does not look bad. However, the major drawback is the 2D graphics. For this reason alone, you can not call it a Rayman Legends complete game. 20 I find that a bit too much.
Difficulty: I would even describe as above average. What is offered in this game, ranging from very mild to severe. Only the level in time are really challenging. Some of these are already very difficult, so 80% of the people they will never meet with security. I myself had to part 50 times and repeat frequently until I managed the best time.
Long-term fun: Sorry, no. Collect all 700 "star" is too much of a good thing, hardly believe that one takes the time to collect all. Multiplayer there is no, only comic competitions make no fun at all.
Recommend this game for the Xbox One has in any case. Alone for the reason, as the game is available for free and is occasionally quite nice. If you're a casual player, you have with the game loose 6 months, and more its fun and has it then certainly not still completely.
