It is not. The game is really beautiful, more than pictures, and very handy Yoshi. Obviously, if we do everything in a straight line without seeking all additional elements (stars, flowers and coins), we miss the fun of the game and it may seem easy. Make 100% on each level is a challenge and I am certain that those who claim to have finished by finding me were not easy quests that offer new levels.
It is the strength of Nintendo games, remain accessible offering of the challenge if we really play the game. This is the case of Mario 3D Land. Many find it easy but few realized that there were new more complex levels once made the game 100%.
Either way, the game is excellent and offers some surprises. It does not revolutionize the genre but still an excellent game. Buy eyes closed regardless of age. Obviously the fans of action games, bloodthirsty and cutscenes, go your way. You are too old in your head to enjoy this kind of game ...
