Kaiketsu Yanchamaru

One day, a mysterious theme park called Karakuri Land appeared in Edo.

In it were various mechanical attractions, built around different themes.

The Nintendo Entertainment System (1983 in Japan, 1985 in the West) revived the North American video game industry after the 1983 crash and established conventions — cartridges, licensing seals, save systems — that shaped the industry for decades. NES collecting is one of the most established retro markets: common titles remain cheap, but a well-known handful of low-print-run games (many from smaller third-party publishers) are among the most expensive video games in existence.

Gamevaro tracks Kaiketsu Yanchamaru for Nintendo Entertainment System with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.

Adding Kaiketsu Yanchamaru to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This NES release dates back to 1987.

Only a handful of market sales have been tracked for Kaiketsu Yanchamaru, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Nintendo Entertainment System titles.

Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
