Good topic Pete.

Godzilla-1998 Sega - 500 units only, so i bought one. This is VERY RARE because of production numbers, although there are probably 6 or more in the Country, but not many.

Other Sega games with the "concave" Headbox shape like Viper Night Drivin, Starship Troopers, Lost World Jurrassic Park etc, considered rare by world standards cause only 1000 to 1200 units ever made of each title. Again, because of the large importing into Australia, we have probably got alot of the rare titles cause we are constantly cleaning out the stocks from all the other countries that USED to have them.

I would probably rate anything with 1200 units or less as RARE, cause by world standards, thats not many to go around to fifty countries etc.

Some titles which were produced in say the 2200 units area, can be considered RARE because of a different reason. Not RARE due to numbers, but RARE due to the fact that people hang onto them and rarely sell very sought after titles. An example is Black Knight 2000. Not rare for units produced, but a bit RARE due to very low sales listings u see, or dont see around. Thats my interpretation anyway.
