I usually avoid these conversations, but an argument that keeps coming up makes me curious...

Everyone keeps saying that the original MM will retain more value due to collectors. Who are these collectors? Almost everyone I know into pinball is more of a player than collector, otherwise TAF should be the cheapest DMD game and Mystery Castle should be worth like triple what it is.

Almost everyone "collects" pinball to play them, but I rarely see posts of "hey, I just finished my WPC-95 collection!"

I think price will eventually sort itself out. I do feel the originals will retain slightly more value, but that is more due to the options (like lighting) that they give.

While I don't deny you any of this, I know a few of those people and they are big into buying brand new games. I would assume a NIB MMR would be actually the more desirable machine for these types of "collectors."
