Grading AES games would be a total different animal......... and not sure WATA has the experts to verify them. The only thing I could think of that would approach high digits graded would be a Euro Kizuna Encounter, a Euro Ultimate 11 and maybe a US Metal Slug 1. All of which haven't seen the light of day in years in a open market. Neo Geo AES appeal is worldwide and with some high rollers. It would be interesting to see.
