Directed by Suda 51, No More Heroes was originally going to be for the XBox 360, but it was later made for the Wii to make use of the motion-sensing controls.
It follows the story of an otaku and wrestling fan named Travis Touchdown who spends all his money on a beam-katana (similar to a lightsaber from Star Wars) Now broke, he meets up with a mysterious woman named Sylvia Christel, who works for the United Assassins Association (UAA) where he accepts a mission to kill the #11 assasin, Helter Skelter. Now, he works to become the #1 assassin in the UAA by killing the 10 assassins above him. After he takes out an assassin, he has to make enough money to pay the UAA to fight the next assassin.
The game is notable for its over-exaggerated blood and violence, which would make it a perfect target for Jack Thompson if he hadn't been disbarred already. So to all the parents out there, DO NOT BUY THIS GAME FOR YOUNG KIDS!!!
Personally, I consider it a very good game, though I think the open world environment didn't have much thought put into it. It would be nice to be able to talk to people, have more store options, basically make it more realistic. A multiplayer option would've also been a nice touch. Still, I highly recommend it, and to all the PS3 fanboys who believe the Wii's "kiddy" this game is quite the opposite.
