Heroic Age of Space Flight (Commodore CDTV, Amiga)

Surprisingly enough, this "game" is stupidly rare. Why? It probably sold less copies than my first album. Anyways, it's just an encyclopedia of space stuff, but I guess for Amiga completionists, it's a rare relic, and hence the price. We're just trying to match what it's sold for, which is actually a fair bit more than what we're asking. Condition: Great , complete in box.
