As odd as it may be (being that I don't play sports games), I had a dream last night of a Ken Griffey Jr. Winning Run NES Pirate cartridge (_it does not exist_, as far as I know, but it was a quite weird dream), and it's got me thinking:
Are there any pirate cartridges/games with high production values that most would consider "must play"?
I guess the rules should be pretty simple. The game should be a unique pirate game (i.e, Somari on the NES) or one-off total conversion (i.e., Speedy Gonzalez --> Sonic 4 on the SNES) that has production values so high/great playability that it should be recommended to the community at large.
What would you recommend?
