If you have a twisted sense of humor, like action games, and are keen to werid details, I fully endorse buying it. I beat it four times personally just because I enjoyed the insane characters, fun combat set-up, and occasional jabs at modern gaming and gamers amongst other things.
EDIT: I hate to sound like an ass, but I think a lot (not all of course) of people who hated No More Heroes simply didn't get it. I think at least some people who got it thinking it's a "serious game", when in fact it's much more of a tongue and cheek parody of "serious game" and many of thier cliches.
Take for example the mini-games. Where you go to collect trash, or coconuts. Some people hated these. I loved them. Why? I think they’re a hilarious joke on the bitch work a lot of modern games dish out. You’re given a clearly demeaning simple task, but your boss always makes a huge deal about it when you get there. For collecting coconuts he tells you there’s big money in them, and that there are worth more than human lives, and that Coconuts are god in Santa Destroy! Then you spend three minutes collecting cocnuts and bringing them back to a drink stand. Cracked me up. Reminded me of the all useless investigation missions in Assassin’s Creed where someone goes on for two minutes and then I just collect flags on roof-tops.
The other thing to note this isn’t a GTA style free roaming sandbox game. It’s a hack and slash action title. You can cruise around the city, but nothing terribly interesting happens until you step on an icon, and go somewhere else.
