Collector interest
The North American NTSC SNES edition of Marvel Super Heroes in War of the Gems, the 1996 Capcom Marvel beat'em up. Released at the very end of the console's life, its US print run was short, making it a genuine NTSC rarity, hard to assemble complete in the cardboard box. Desirability rests on this end-of-cycle scarcity, on the Capcom Marvel coherence on SNES (the other title staying Japan-only) and on demand boosted by the current fame of the Marvel characters.
