The last ten years seem to have really embedded the idea that we should get our money back when selling a game. I suppose with the rising price and decreasing quality of the Stern games, the added pressure on the prices for classic DMDs has contributed as well in the last couple of years. But really should we be expecting this? How many other two,three or five thousand dollar items can you buy and not expect to loose?
I suppose the collectibility aspect and lack of replacements, increasing demand creates the opportunity to buy, play, and sell for similar money.
This might change for some classic pricing with PPS and Medieval Frankegame - and quite topical given the AFM discussion here and the prices being sought given this will most likely be the next or one after that game. I suspect $15K AFMs will disappear then too.
