For me, few producers are as criminally overrated as Suda 51. That Killer7 became a cult hit is just a demonstration that if something looks "different", quality is immaterial in the eyes of many.
NMH came out to amazing reviews. Ended up in the 80's. And while the game does not deserve great scores, it is actually a surprisingly fun game. As usual, a Suda 51 game relies far more on style than on actual substance --- but (and this, admittedly, is not high praise) this is so much better than anything he's done before.
You play loser geek Tommy Touchdown. You end up buying a light sword that allows you to become an assassin. Not just an assassin, but an elite assassin. Your goal is to take down the top 11 assassins.
But, it's not just as easy as going along and just killing the assassins. To fight an assassin takes money. So, in addition to killing assassins, you have to raise the money to be able to actually fight them in the first place.
The controls are one of the better uses of the Wii's motion control on the market. You have to move the controller around to trigger grapples, hit finishers, or win weapon melee clashes. The gore is actually so over the top that it is comical. You hit a finisher and a bloodbath ensues --- followed by a lot of coins.
The game, itself, is flawed. The map is a nightmare to use. The battles to get to the assassin you're fighting tend to get repetitive as the enemies are "special", if you catch my drift. The mini-games to collect money, while a cute CONCEPT, is not a really funny gameplay mechanic.
It's a pretty decent Wii game --- but the Wii is lacking those, so it's worth a shot.
