Blockbuster's second Video Game Championship contest, for SNES and Genesis, ran nationwide in 1995. Stores had to destroy the cartridges after the contest. Someone made 100 reproductions to help completionists fill a gap in their collections. About 40 are left.
Best part, it sounds like the buyers will have a high score contest of their own after the lot is sold out. While these things are not authentic originals, they are a $US60 way to take care of a missing cart that probably isn't going to be found at an affordable price anytime soon.
The makers have given this reproduction of Blockbuster World Championships II - the Genesis version only - an authentic clamshell case with a hand-numbered insert; a Sega/Acclaim style cartridge casing and a shrinkwrap sealing "more of a novelty than anything else".
This listing of cartridges pegs an authentic specimen's value at around $US2000.
