Sonic Adventure

Sonic Adventure was the first 128 bit Sonic game and was originally released to the Sega Dreamcast on November 28th, 1998 before eventually being updated for the Nintendo Gamecube as Sonic Adventure DX: Director's Cut. The DX version added RPG elements while keeping true to the action style of the series. One area is a casino that features an action stage that plays almost like Sonic Spinball. The game's popularity resulted in a few sequels. It became a big hit as one of Sonic Team's first big 3D video games (after NiGHTS: Into dreams...). The graphics, though, are nowhere near as good as possible on the Dreamcast, although the lighting on the game was made better when Sonic Adventure: Director's Cut was released for the Gamecube. Selling over 2.5 million copies, it is the Dreamcast´s most successful game.
