Collector interest
Altron's N64 take on hanafuda, kept strictly Japanese. Its price rests on two things: a tiny print run from a minor publisher and an audience limited to players who know the traditional card rules. No Western release, no localization, making it a typical entry in the Japanese board-game niche, where genuine scarcity far outstrips demand, so the value comes mostly from how few copies exist rather than any clamor for it.
