Ys IX: Monstrum Nox

While imprisoned in Balduq, Adol is cursed and becomes a Monstrum.

With his newfound powers, he must stop the Grimwald Nox from consuming the city.

The PlayStation 4 (2013) cemented Sony's dominance of the eighth console generation, with a library exceeding 30,000 titles once indie and digital-only releases are counted. Most PS4 games remain affordable for collectors, but limited physical print runs — particularly from smaller publishers and later in the console's life cycle — are starting to see steady price increases as digital storefronts eventually wind down support.

Gamevaro tracks Ys IX: Monstrum Nox for PlayStation 4 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 Ys IX: Monstrum Nox 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 PS4 release dates back to 2021.

Market insights

Only a handful of market sales have been tracked for Ys IX: Monstrum Nox, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common PlayStation 4 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.
