Pugsley, surely an investment than a game. :P
A crappy (even considering NES limitations) port of the first SNES Addams Family.
And yet the NES version was ported, with even more stuff chopped out, to the Game Boy. Yet I had that one as a kid, so I'm for the nostalgia it's probably a good thing I rebought the game CI already. I hear that game is one of the rarer GB (NintendoAge 6/10) games as well, which means only time before scalpers get to it. I picked up the rare games I wanted from that list already, save for the already gouged Spud's Adventure, which I bought in Japanese for cheap.
As much as I'd love to see ZAS on a real original Game Boy, that's well into flashcart territory these days, as well as a couple other Japanese obscurities.
All the 1992-1994 games? Even the first-party games, which all seem fairly common and very cheap these days? (not sure if it's even still possible to buy Kirby's Adventure sealed for original price these days... as long as you don't mind if it's the Quebec version?)
