On the PS3 is NBA Elite 11, (Its not that good)

Gamma Attack for the Atari 2600, literally only one copy is known to exist, and a collector has it

Probably Takeshi's challenge.

Maybe Drac's Night Out on NES or Nintendo World Championship also on NES.

If not, then AirWorld on the Atari 2600 because we are pretty unclear on whether or not it even started production, but if it did, then it's likely that it was put into a cartridge for testing purposes.

I made a Dinosaur themed quiz game not too long ago and I never released it anywhere so probably that

 

[Doc X]

The PAL version of Kizuna Encounter: Super Tag Battle on the Neo Geo AES. Only five copies of this game are known to exist nowadays.

I have heard legends told of a game called "TRIPITAKA," which is a spiritual successor of sorts to "Cosmology of Kyoto." I believe that to be the rarest game of all time.
