Neptunia: Sisters vs. Sisters

The "sisters" get their long-awaited star role in this genuine Neptunia series spin-off!

The four younger sisters rise up to take back their share of the portable games market stolen by the mysterious smartphone called "MagiPhone." The character models that decorate game scenes are all-new, and the characters are cuter than ever!

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 Neptunia: Sisters vs. Sisters 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 Neptunia: Sisters vs. Sisters 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 2023.

Only a handful of market sales have been tracked for Neptunia: Sisters vs. Sisters, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Xbox One 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.
