Koneko Mo Issho

Koneko mo Issho is a Video Game developed by Bomber Express and published by Sony Computer Entertainment Inc.

It was released on January 27, 2000 for the PlayStation, and is the second game in the Doko Demo Issyo Series.

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 Koneko Mo Issho 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 Koneko Mo Issho 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 2000.

Market insights

Koneko Mo Issho has a steady sales history on the tracked marketplaces, meaning enough copies circulate to establish a reliable market price.

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.
