I finished the main Legends "story" with 570/700 lums. I still need to do a chunk of Origins levels and some Invaded levels.
Some thoughts:
+ game looks beautiful (some visually less interesting worlds too though)
+ excellent soundtrack
+ collecting is fun and rewarding
+ plays smoothly and controls nicely
+ music levels (much to my surprise some of the most enjoyable stages in the game)
+ fun, light hearted, vibrant and happy "make you smile" stuff
+ varied gameplay
- definately easier than Origins. In most cases, little effort is needed to get gold and collect everything
- the new checkpoint system means you get lazy as a player
- a bit of a mixed bag without any overall focus, more a collection of ideas
- too many Murfy levels and too few traditional levels
It's apparent that this game had a different audience in mind when it started as a Wii U exclusive. It's more meant as a family friendly touch/gamepad "let's all play together and have fun"game than a "hardcore" platform game (with the first Wii U trailers, it was advertised as such too iirc).
It's a different game. Although you will not hear me tell you that Origins was the pinnacle in platform and level design either. In a way, the more varied approach of Legends could have worked even better than Origins (which had a lot but quite similar levels) but the development team didn't quite manage to pull it off.
In the end though, i really enjoyed my time with Legends. My games don't need to be really hard to be fun. I wouldn't have mind one or two more worlds and a tad more challenge but i think it was meant, on purpose, to be a different game than Origins.
Not the corcker i would have hoped for then but i would still give it 8.5 or 9 out of 10. Because, in the end, i had a good time with Rayman Legends.
