I have beat this game multiple times on console (don't hurt me), and I can easily say that this is one of the best platformers ever...hands down! Whenever people hear "greatest platformer ever" people always point at the original Mario games, Super Mario Galaxy, etc. However, this easily joins among their ranks.
This game is a breath of fresh air in the platformer genre. Along with its counterpart Rayman Origins (which I have also beat), they are both really refreshing platformer games because of their unique style, in graphics, gameplay, and level design.
Firstly, the game is visually stunning. The game uses an engine called the "UbiArt" engine, which is used to easily animate any image. The animations in this game are flawless given the many different movements that Rayman can use. Plus, the game feels INCREDIBLY smooth, and there are no visual flaws whatsoever. If I was to ever to die in this game, I cannot fault the game for choppy frame rate... I always blame myself!
Speaking of which, the game has a difficulty balance that can accomodate both new players and old players. Some levels can be a breeze, but then others you can die A LOT, especially some of the later levels.
The level design is really good. Like most platformers, each world typically has a "theme". In my personal opinion, I believe that the "Fiesta de Los Muertos" world in Rayman Legends is the best, clearly because the level design is so great in every single level (if you play the first level at the world, you will see exactly what I mean). What a lot of platformers truly fail at achieving is creating MEMORABLE levels, and Rayman Legends has at least a few memorable levels that will be stuck in your head. Even the boss battles are really great!
The gameplay is also really addicting, with plenty of different moves to learn. This can range from a series of simplistic punches, all the way to cartwheels (a slightly more advanced move). While the objective is to complete a level, there is also a ranking for each level to grab a both a certain number of lums and "teensies". Lums, unlike the last game, are accumulated and can be used to unlock new variants of characters. Plus, lucky tickets unlock plenty of different things, including updated Rayman Origins levels!
...and the multiplayer...oh my....the multiplayer is GOLDEN!!!! This game easily has the most fun local multiplayer in a long while! The multiplayer is perfect for anybody, whether you want to play seriously or if you want to troll your friends. :)
Another memorable part of the game, even though it is not as prominent, would be the soundtrack. The soundtrack really compliments the game in different ways, and I had a couple of tunes stuck in my head. Overall, the game can last you quite awhile, maybe about 15-20 hours to complete everything (depending on how good you are). What can also add to the length would be the daily and weekly challenges, where you can REALLY hone your skills.
There are a few flaws, given the overall grand scheme of things, but hardly hold this game back from sheer greatness. I think that there should have been more minigames along with "Kung Foot" because "Kung Foot" isn't necessarily my favorite part of the game. Also, I think that there are also too many "clone" characters (variants of Barbara in particular).
To whomever might read this review, I would not even hesitate getting this game. Play it and love it! You won't regret it!
