Sonic Adventure took Sonic to an amazing level, and it only took 5 years of Sega Saturn failures. The first thing Sonic does is fight a monster called "Chaos". After beating Chaos, the camera turns to Eggman, who ominously tells himself Sonic has no idea what he is up against... the perfect start to the game. Sonic then goes off to rescue Tails from a plane crash, starting the first level. Emerald Coast was a beautifully rendered beach with a beautiful theme and HUGE 3D ACTION! The camera shifts and Sonic is suddenly is being chased by a giant whale! After that he runs through a tight cave... and then finally rescues Tails! After a happy reunion, Eggman steals Tail's Chaos Emerald and feeds it to... Chaos the monster. Congratulations, you can now play as Tails! He can fly! His levels involve racing Sonic and Eggman (Just like in Sonic R!), and thats about it. The best thing about Tails was his inspirational motto, "I want to fly high! I shall belive in myself!". After Tails was Knuckles, who had a totally different story. One night he was rethinking his life and why exactly he was guarding the Master Emerald, when somebody steals the Master Emerald (way to go, Knucklehead)! His levels are composed of finding the Master Emerald pieces. Knuckles wasn't nearly as good as Tails. After Knuckles comes Amy Rose, Sonic's... girlfriend. Her levels focused on platforming while avoiding a robot that decided to chase her. Maybe a 6 year old girl would find Amy and her obnoxious theme song cool, but the teenage nerd reviewing this finds Amy very annoying. Big was next... and Sega really should avoided this idea while in development. Big is a BIG "cat", according to the Sonic Team. He really looked like a purple bunny-bear creature. His whole goal was to find his pet frog... Froggy (what a clever name!). It was torture watching him trudge to some water in the great zones Sonic and Tails enjoyed. Twinkle Park was only a lake for Big. For Sonic it was a bumper car ride followed by intense platforming, and the great voices Sonic, Tails, Amy, E-102 Gamma, and Eggman made Big even worse. In a dumb voice Big constantly shouts "FROGGY! WHERE ARE YA!?".
