Sonic 3D

Seven levels separate Sonic from the final showdown with Robotnik.

Sonic 3D was the last Sonic title released for the Mega Drive, the only platforming presence of the blue blur in the Sega Saturn, and one of his rare appearances in Personal Computers.

The title, considering the era it was released, is somewhat misleading, as instead of full blown 3D graphics it uses an isometric view where Sonic can move not only forwards and backwards, but also left and right.

Gameplay is much slower when compared to other games in the series, and the number of badniks is reduced to five in each section.

As usual, when Sonic destroys one badnik, an animal leaps free from its insides, but this time Sonic has to pick him up and lead them to an interdimensional ring.

While they can be taken one by one, exploring the level with all five allow the player to reach for otherwise inaccessible continue tokens.

Unlike all other previous games, time isn't a requirement: if the player completes a level in more than 10 minutes, it would only mean there would be no time bonus at the end.

Finally, to collect all seven Chaos Emeralds, Sonic first must find Tails or Knuckles and offer them at least 50 rings.

Sonic 3D for Sega Saturn is currently worth €114.29 loose, €58.07 complete in box, and €69.97 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Sonic 3D 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 3D, loose is €114.29 and CIB is €58.07 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.
