Others have said the same thing, but you are better off that the deal fell through.

I bought my first game on eBay. I drove from Chicago to Louisville to pick it up, and the guy had the game set up and let me try it out to my satisfaction before loading it up. I overpaid and was later kind of bitter about it, but it was my fault because I was excited about buying my first game. I couldn't blame the seller at all, as he let me inspect the game, play it, etc. before taking it home.

I have sold only one machine on eBay. The guy came down from Madison, so obviously it would've been impractical to test the game before bidding. He won the auction, but I insisted that he check out the game and play it as much as he wanted before taking it. I even told him he was not obligated to buy the game if he thought I had misrepresented it in my ad. I'd rather not sell a game to someone than have that person feel that I ripped them off.

If someone gives you a hard time about wanting to test a game before buying it, you are better off not doing business with him, in my opinion.
