I remember when the game was shown off. The whole Killer 7 heritage was good and bad for it's reputation.
I never played Killer 7 myself, but I liked the combat of No More Heroes. Star Wars meets Japanese Samurai Weirdness.
The sandbox game-play of the main hub-world was pretty awful. There was really nothing to do besides a few odd jobs.
Despite that bullshit, I fucking loved the boss fights. Each rank fight was epic and I couldn't wait to see the next challenge.
I also loved the game's perverse humor.
