The storyline of Sonic 3D is as follows: Sonic goes to visit his friends, the Flickies, on Flicky Island. He gets a surprise when he arrives, though. That evil Doctor Robotnik has surfaced again and is using the special location-warping powers of the Flickies in his never ending quest for the Chaos Emeralds. Turns out that the Flickies posses the power, when grouped in fives, to warp from location to location using ring portals. Sonic decides to free his friends from Robotnik and crush the madman's ambitions.

Released two years after the Sonic series ran out of gas, 3D Blast attempted to transition Sonic into the 3D universe. This is by far the most technically superior Sonic, but also the least fun! Graphically, it's a visual masterpiece; perhaps the best looking Genesis game ever. Inspired by games like Marble Madness, the 3D multi-tiered landscapes are lush, clean, and detailed. The high-resolution 3D characters are animated smoothly, and the seven zones are inspired by the original Sonic games.

Gameplay involves running around different areas collecting rings and power-ups, jumping on robots, and gathering up the furry animals that are released. When you have them all (usually about five), you take them to a big ring that teleports you to the next level. Knuckles and Tails make appearances in the game too, and if you locate them, they will give you rings or take you to a bonus stage. The bonus stage, a rickety bridge over lava, looks cool but is only moderately fun.

Sonic 3D Features:

• Features 14 levels.
• Variety of power-ups.
• Hidden bonus levels.
• New environmental effects.
• New Blast Attack.

With 3D, this game is even marvellous! The game requires a bit of thinking so you can manage to zoom to the end. Getting Chaos Emeralds can change the ending a bit. Also, you have to collect these cute birds called Flicky in order to teleport you to the other levels! These creatures are now changed into enemy robots by Robotnik so you have to smash them to reveal their own body.

Sonic now has a Blast Attack that will help him defeat Robotnik's minions. Environmental effects, like rain and fog, add new gameplay elements. Save the Flickies and collect the Chaos Emeralds before Robotnik does in SONIC 3D.

Sonic is now transformed once again into an outstanding 3D game! This time, if you're too familiar with the 2D Sonic games, then I'm afraid you'll need a little time to be okay with this game.
