Quoted from jgentry:For the poeple that love MM and bought it for that reason it won't matter because it won't be for sale anytime soon. What in the world makes you think this game will take a 25% drop or more when all other new games do not unless they suck. It's MM, it's not going to suck.
I think you are right that most buying MMR won't be selling anytime soon. Most bought it because the game play and rules are a known commodity, which is different than new games from other manufacturers and they want/expect to have a Medieval Madness for a long time. Whatever the resale hit is won't matter, because the game won't be for sale. (This is why as an MM owner, I didn't really care if my game was valued by others at $18k, $10k, $8k or whatever, because I'm not going to sell it anyway).
If there are issues with the board sets or the games that aren't resolved quickly, then you may see some discounted sales (like WOZ with early light board issues), but I suspect this isn't very likely.
However, there are apparently a lot of people buying an MMR just based on the reputation of MM. Some in this group may find they don't like the game Medieval Madness as much as they think and may have to sell at a steeper discount than you might expect because few that want the game (that don't already have one on order) are going to buy anywhere near $8k since (a) they won't be eligible for any warranty coverage and (b) if you are going to spend that much, you might as well buy a new one. And since PPS says MMRs are going to be produced as long as there is demand, it may take longer for HUO copies to sell without a significant discount.
I don't know if 25% is the right figure, but looking at recent WOZ sales, it may not be too far off. The higher the purchase price, the steeper the depreciation hit.
