It's hard to say what it would go for. There are a handful of collectors that would pay $1500 on the spot for the game, I am sure of that. As far as rarity, it is nearly impossible to locate, and since the two confirmed ones are in collector's hands, it's not going to be possible to see what it would go for on running auction until someone puts one out there.

There are not too many Genesis collectors, and this definitely does not have the lore behind it like the NWC. Rarity does not always equate to value. I think as a running auction, no reserve, it would hit $1200-1600 MAX.
