This game is a must own for all Wii owners. I have not played the other two games mentioned. However, the visuals are awesome (best on the Wii IMHO), the game play is exciting, the story is top notch, and the production values are A+.
I am a hardcore PC gamer and this game stands up against that level of gaming.
On hard it took me 7.5 hours to beat the game. That does not include finding all the collectables. Expert and Impossible mode are also available after you beat the game once.
Beyond story mode, challenge mode will easily add another several hours to the game.
