* The small version can be found on ''Gran Turismo HD Concept'', ''Gran Turismo 5 Prologue'' and ''Gran Turismo 5''. While the former game is extremely rare to find (due to the fact that it was delisted from the PlayStation Store on September 30th, 2007, though retail copies of the game exist in an installation disc form, albeit they're very hard to find), the latter two can easily be found either via online shopping websites or via thrift stores.

'''Availability:''' Rare for the variant used on the European and North American versions of the PlayStation game ''Gran Turismo 2'', but the game can still be found in used video game stores, pawn shops, flea markets, thrift stores and/or eBay listings. As for the ''Gran Turismo 2000'' variant, it is known to be extremely rare, given that the game was only released in a form of a demo that was given away to attendees during the PlayStation Festival 2000 event in Japan from February 18, 2000 to February 20, 2000. Given that the demo only had a limited amount of copies available and a lack of other releases, it can be considered the rarest and most sought-after game in the ''Gran Turismo'' franchise.
