I think people are just confused, not attacking you. This auction is not very clear. Do you want people to pay you with actual games, instead of PayPal or money? Does that mean I can bid with cheap copies of NHL '04 or Pac-Man on Atari 2600?
And it's odd. I've never heard of such a thing. Ranting on your potential customers for being understandably confused, is probably the last way to make a sale, though.
