Shinobi

You control a shinobi, Joe Musashi, who must battle his way through each level in search of hostages which must be rescued.

You have shurikens, kicks and punches to defend yourself with, as well as powerful ninja magic which can clear the screen of enemies in one go.

Sega's Game Gear (1990) was a technically capable handheld competitor to the Game Boy, notable for its full-color backlit screen — a real advantage at the time, offset by famously poor battery life. Its commercial underperformance against Nintendo's handheld means smaller print runs overall, and complete, well-preserved cartridges (the plastic shells are prone to yellowing and cracking) are a genuine niche within retro handheld collecting.

Gamevaro tracks Shinobi for Sega Game Gear 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 Shinobi 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 GG release dates back to 1991.

Market insights

Shinobi 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.
