So you fancy yourself a video game collector? Do you own the Donkey Kong Country Competition Cartridge, manufactured specifically for the Blockbuster World Videogame Championship II in 1995? Probably not, since according to the auction notes, only "2500 copies" were ever made. There's currently just over 40 mins left, and bidding for this piece of history has already exceeded $500. Expect the sniping to commence closer to the actual auction ending, because most gamers (at least those who play Counter-Strike or Halo 3) seem to be pretty good at it.
