Not saying this isn't a cool find, but don't use KLOV as a accurate guide to rarity (or their claim to rarity as a guide to value). They use the woefully outdated VAPS.org as the source of info. To show how whacked it is, look at the listings for Quantum and Major Havoc. Both of these games are rare and command high prices in good condition, but KLOV lists them as common. Games people don't collect because they're not that great (like my Bally/Midway Power Drive) are tagged Very Rare.
