Absolutely insane. I am not sure why anyone would care to buy this. The game was made for atari by an independent person. The game was not even known to exist until someone bought it at a yardsale in 2007 and verified that it was real. I do get paying more money if someone found the original game disk from the company (like the test copy) for a popular game – and by more money I mean maybe $100 to a huge fan. But 10k on a game that no one will ever play and no one even knew existed?
