To be honest, I do. I dig the living shit out of it. When I see something for NMH2, I jizz in my pants..
But let me elaborate why I love it. (Just so you don't think I'm crazy.)
First off, from what I've played of it, it seems VERY addicting. Slice this guy, throw that guy, move on. It just seems so... so simple, yet so fun.
Second, the game itself is just a joke. I love it when a game decides not to take itself seriously, and more games should learn from Suda 51's works.
I have the game, and I've beaten it so many times, I could likely recite the script from heart.
So there ya go.
In all seriousness, though, if you don't love No More Heroes, you'd better call a doctor, because you may be dead inside.
