Vid - great selling advice! I would like to add one small thing when selling that one might consider -
This happened to me once. I had a buyer come and play a game of mine that was for sale that
he had played all the time when he was younger. He played the game for a good 20 minutes + and
when he was done, he had changed his mind about buying. He said he had "beat it like a rug".
Ever since , I've maintained a "3 game rule". That's all the time I'll allow anyone to play a game.
That may even be too long. You don't want them to "scratch that itch".
