Neo Geo AES · 1991
About this game
Players get to choose any one of six monsters (four in the 16-bit ports) for battle, and two players can join forces to fight the monsters together.
Battles end when one of the monsters is pinned for a three count or if time expires (in which case the player loses).

The game consists of 12 total levels: the player first must defeat all six monsters, with the last monster being oneself, but in a different palette.
Then the player must defeat the six monsters again, in the same order, but this time in different cities
About Neo Geo AES
SNK's Neo Geo AES (1990) was marketed as the ultimate home arcade experience, using the same hardware as SNK's arcade cabinets — at an extraordinarily high price for both the console and its cartridges. That exclusivity is exactly why Neo Geo AES games remain among the most expensive in all of retro collecting; several titles routinely sell for well over a thousand euros in good condition.
Gamevaro tracks King of the Monsters for Neo Geo AES 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 King of the Monsters 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 NEO release dates back to 1991.

Rarity & condition
Only a handful of market sales have been tracked for King of the Monsters, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Neo Geo AES 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.
