Collector interest
Japanese edition of Koei's airline-management sim, released in late 1993 as Air Management II, the basis for the Western Aerobiz Supersonic port. Confined to the Japanese market, it stands out for its fully Japanese interface and plastic case with spine card, sought by Koei sim collectors. The low loose price contrasts with high complete and sealed valuations, a sign of a modest Japanese run and complete copies that have grown hard to find.
