Collector interest
The US NES version of the cult Capcom title built on the grapple arm without conventional jumping, on the console's flagship market. Widely distributed at the time, the loose US pressing stays affordable, with value concentrating on graded sealed copies and clean CIB whose cardboard box, quick to warp, makes nice examples fragile. The NTSC version keeps the aura of an atypical action design that sustains steady demand beyond mere scarcity.
