Sonic Adventure

Sonic Adventure is a video game created by Sonic Team and released December 23, 1998 in Japan by Sega.

Another version of the game, Sonic Adventure International, which had bug fixes, was released on September 9, 1999 in North America, October 14 in Japan and Europe, October 18 in Belgium, the Netherlands, and Luxembourg, and December 3 in Australia.

It is the first full 3D game in the main Sonic the Hedgehog series.

Published for the Sega Dreamcast, this game was supposedly the most impressive display of graphical prowess the genre has ever seen in that time period, and it put on a very impressive show.

This was the first game in North America and Europe where the main villain was called Doctor Eggman. His name in both of those locales was Doctor Ivo Robotnik prior to this release. In manuals, he is referred to as "Doctor Eggman aka Doctor Robotnik", but Eggman became the dominant name.

It was rereleased on Nintendo Gamecube under the title Sonic Adventure DX: Director's Cut on June 17, 2003 in North America, June 19 in Japan, and June 27 in Europe. The update includes enhanced graphics and the playability of every Sonic the Hedgehog Game Gear game.
