Hey, I see that you are up this thread every few days and that got me curious about these games: especially Amazing Tater. It seems like this has been a hard sell for you. I was looking at gamevalue now at the prices and what I realized is that the $1,699 current value is based on 1 sale. Pricecharting has it at $1100 with no sales.
Something interesting about that 1 sale for $1,699, did you know that that was an auction, which started out at .99. I can't tell you what to do, but maybe take your cue from that guy. If I were you I would create an auction, I would pay money to try to get the game to the top of ebay searches. I would maybe run the auction 2 weeks, and maybe have it end on the 10th of the month or something. The fact is you have to create an environment for buying (and one thing I will tell you) the difference between an auction and buy it now, is that with an auction, people know that it WILL sell, especially if you list it at .99 and get bidding going fast, so the people that WANT this game, but aren't buying it now, know that if they don't act now it will be gone. You have the only listing for this game, and there hasn't been another listing in a while, so if I were you I would list it and hope that people realize that it is either now or never, and i bet you you will get significant interest in it.
My two cents.
