Sonic the Hedgehog

Sonic rushes through levels with incredible speed, allowing him to traverse loops and jumps with ease.

The plot of the game is simple.

Robotnik has captured many of Sonic's animal friends and trapped them inside robots.

Fortunately, Sonic can free his friends by destroying the robots with his spin attack.

Robotnik is trying to control the all-powerful chaos emeralds.

Sonic must grab them before he does in the 3D rotating bonus levels.

Sonic's weapon is his spin attack; while jumping, Sonic destroys hostile robots by touch.

Throughout the platforming levels, Sonic collects numerous rings.

If Sonic is hit by an enemy, all the rings he's carrying fall out and scatter around; Sonic can quickly grab the rings back before they disappear.

If Sonic is hit while not carrying any rings, he dies.

Collecting 100 rings gives Sonic an extra life.

There is also an invincibility bonus which temporarily protects Sonic from all attacks.

The game is divided into several "zones", each of them containing three levels.

At the end of each zone, Sonic confronts Dr.

Robotnik in a boss fight.

Sonic the Hedgehog for Xbox 360 is currently worth €22.22 loose, €19.81 complete in box, and €25.50 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Sonic the Hedgehog has a steady sales history on the tracked marketplaces, meaning it trades hands regularly and isn't considered particularly rare.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Sonic the Hedgehog, loose is €22.22 and CIB is €19.81 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.

The PAL version of Sonic the Hedgehog is currently worth €22.22 loose, versus €12.22 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
