Sonic Unleashed
Xbox One · 2008
About this game
In this version of Sonic Unleashed Eggman manages to defeat Sonic, using the tremendous power of the Chaos Emeralds to entrap him.
The sheer force of the attack had also broken down the planet into pieces, and released the mysterious dark creature called Dark Gaia from within the depths.

Eggman then leaves Sonic trapped along on the broken planet, along with the now-drained Chaos Emeralds.
It is now up to Sonic to retrieve and recharge the drained Chaos Emeralds, save the planet, recapture Dark Gaia, and defeat Eggman for good.
The game features both daytime levels, which focuses on Sonic's overdrive speed, and nighttime levels, which are more combat-focused, as Sonic transforms into a fearsome-looking yet powerful Werehog beast, as a side-effect of the Chaos Emerald attack he had suffered from.
The PS2 and Wii versions feature an almost completely new mix of levels as well as a different game engine.
About Xbox One
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 Sonic Unleashed 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 Sonic Unleashed 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 2008.

Market insights
Rarity & condition
Only a handful of market sales have been tracked for Sonic Unleashed, 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.
