It's Grasshopper going back to it's roots. If you liked Silver Case, Flower Sun and Rain, Killer 7 and the first No More Heroes, give it a try.
If you liked the games that came after it during their more corporate stint, give it a pass. Not a single of their games ever had anything beyond serviceable gameplay.
Apparently the Fire Pro Wrestling DLC Suda wrote is also tied into No More Heroes 3...
