My list for Super rare games I want to see surface:
Total Recall - that design drives me crazy. I need to see it in person to experience how on Earth it would play. The upper PF is definitely split control.
Also I seriously need to know how they broke it down for transport... there is NO WAY the dual cab stays together.
Total Recall would be a Pinball Circus level novelty game just for the sake of "how far can we take it"?
Goin' Nuts - with the previous post we now know 2 pairs of games are held up with collectors holding them for trade fodder. Lame IMO...
Goin' Nuts should be remade. It's such a unique, beloved game with an ingenious twist. People would LOVE to have it! It also could use lots of finishing touches.
Hypnox - the backglass is so incredible I want to see the game purely because of how incredible the art package must be. Hope pictures surface.
Another game that hasn't come up that actually has a real chance of popping up randomly: Varkon by Williams only 72 or so made
