This is GOTY material, and I mean "GAME of the year", not "game trying to be a movie of the year" like the crap that usually gets nominated.
Not only is it an all around fantastic experience, but the hard mode is actually hard. This harkens back to a TRUE old school game, one where there's just an insane amount of actual gaming content to digest. I've just procured my 2nd princess and now this one has her own quest for me.
And the other kings are awesome. The short cutscenes that play before you fight them are well done and wonderfully bizarre. This game has everything, action, strategy, micromanagement, the works.
Every Wii owner should buy this game, period.
Pro, stop playing Wii Sports Resort and buy this. :p This is one 3rd party that ain't making excuses.
