Collector interest
Capcom's sequel to the first NES G.I. Joe, released in 1992 in the US only and even rarer than the first entry. Reduced distribution, end-of-cycle US NES, and the combination makes a US CIB genuinely hard. The cart is an acknowledged grail for Capcom NES collectors, and graded sealed prices climb sharply, sustained by real physical scarcity more than by mass nostalgia.
