So here's the thing with Blockbuster exclusives, every Blockbuster in North America got anywhere from 5-15 copies. Let's just do 5-10 to keep it simple but bear in mind there's more copies out there.

At its peak in 2004 Blockbuster had over 9000 stores world-wide, but 4500 in North America. Let's just say it had 3500 in 2000. If each of those 3500 stores got 5-10 copies of these games each how rare do you think they actually are? At least 17500, but upwards to 35000. The reality is many more were likely produced. Clayfighter remains the most well known of these titles but a title like Razor Scooter is the same thing - small distribution through Blockbuster only but a far cheaper price tag 25 years later. Neither of these titles is particularly good but one is even semi-redundant as there's a common retail copy of the game missing a small amount of exclusive content.
