About Sega CD
Known as the Mega-CD outside North America, the Sega CD (1991/1992) was Sega's CD-ROM add-on for the Genesis, offering full-motion video games that felt cutting-edge at the time but haven't all aged gracefully. Bulky, fragile packaging and a relatively short commercial life make complete Sega CD sets — case, manual, and the disc itself — a meaningful step up in difficulty from Genesis cartridge collecting.
Gamevaro tracks Wonder Dog for Sega CD 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 Wonder Dog 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 SCD release dates back to 1992.

Rarity & condition
Only a handful of market sales have been tracked for Wonder Dog, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Sega CD 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.
