A unique and mature Wii experience and you need to play it.
Sure the Nintendo games like Super Mario Galaxy are amazing, but it tends to get old playing with the same characters in every game you buy. The sports games that take advantage of the Wiimote are highly innovative and it's usually what my friends and family pick to play against eachother - but ENOUGH already with the repetitive sports games.
For me, No More Heroes was a godsend. Finally, a mature game that was fun to play and was completely original.
When I started to play, I was surprised by how easy it was to get in to. Though the graphics weren't the best, it had it's own charm. Since I bought an HDTV, I have been extremely picky about graphics, but I love the colors, and the characters style and the whole theme of the game.
The exaggerated blood, the beam katana, the coins, and the excellent controls made the killing sprees really fun and really addictive.
The game play sometimes got repetitive, but it never really got old. For me, it was somewhat reminiscent of retro gaming - just in the simplicity of what you have to/can do to beat the game. The story itself was really entertaining. I "LOL"ed quite a few times watching the cut scenes - the characters were really interesting and though it was mature comedy, it didn't get too sleazy like some games do. AND, there were times when Travis would get called on his cell phone in the game, and the call would come through on the WIimote's speaker - if your volume is turned down on it, you'll have to hold your Wiimote up to your ear like a cell phone and I got the biggest kick out of it.
It doesn't take very long to beat, but you get to play enough to be satisfied - until NMH2 (hopefully).
I'd recommend this game to absolutely anyone.
