Slime Shiyou

Slime Shiyo (aka Siraimi Shiyou!) is a breeding simulation game released for the Playstation one console, in the game the player has to breed a slime, some sort of alien creatures that are born from an alien plant and depending of the fusions and the power used to breed them they can evolutionate in a way or another.

The game features 4 different terrains and the gameplay starts when the player plants the seed and the plant starts to grow, after that he can use the powers of lightning or wind to make different things to happen.

The original PlayStation (1994) brought CD-based gaming and 3D graphics to the mainstream, ending Nintendo's console dominance of the previous two generations. It's now firmly in "retro collecting" territory: original jewel cases with intact manuals command a real premium over disc-only copies, and several RPGs from its later years (when Sony deliberately courted the genre) are among the most expensive commonly-collected games from the era.

Gamevaro tracks Slime Shiyou for PlayStation 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 Slime Shiyou 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 PS1 release dates back to 1996.

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