Sansan

Sansan (サンサン) is an online service allowing people living in Japan to play the abstract strategy board game Go with other subscribers over the internet on a Windows PC.

However, at its launch in 1994, a version for the Sega Mega Drive was also made available.

Known as the Mega Drive outside North America, the Sega Genesis (1988/1989) was Sega's most successful console and Sonic the Hedgehog's original home, fueling the "console wars" era against Nintendo's SNES. Genesis cartridge collecting is well-established: common sports and platformer titles are affordable, while sports-license and later-era games with smaller print runs can carry a meaningful premium.

Gamevaro tracks Sansan for Sega Genesis 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 Sansan 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 GEN release dates back to 1994.

Only a handful of market sales have been tracked for Sansan, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Sega Genesis 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.
