Ninja Gaiden Sigma

Ninja Gaiden Sigma, stylized as Ninja Gaiden Σ, is an action-adventure game developed by Team Ninja for the PlayStation 3.

It is an enhanced port of Ninja Gaiden, originally released on Xbox in 2004, and is the second expansion to the game after Ninja Gaiden Black.

Microsoft's Xbox One launched in 2013 alongside the PS4 and leaned heavily into backwards compatibility and subscription services like Game Pass. Because so many Xbox One owners moved to all-digital libraries, physical Xbox One cartridges — sorry, discs — in good condition are comparatively less common on the secondhand market than their PlayStation equivalents from the same era.

Gamevaro tracks Ninja Gaiden Sigma for Xbox One 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 Ninja Gaiden Sigma 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 XONE release dates back to 2007.

No market sales have been tracked yet for Ninja Gaiden Sigma — this could mean it rarely changes hands, or simply that Gamevaro hasn't recorded a sale for it yet. Be the first to add it to your collection.

Condition matters a lot for collector value: loose (cartridge/disc only), complete-in-box (CIB, with original packaging and manual) and factory-sealed copies are tracked separately because the price gap between them can be significant, especially for older releases.
