Valve Software's unique first-person shooter/puzzle game Portal (part of the developer's Orange Box) took home top honors as the Game of the Year at the 8th annual Game Developers Choice Awards. Portal won three awards, including Best Game Design and Innovation.

2K Boston/2K Australia's BioShock also won three awards: Best Audio, Best Visual Art and Best Writing. Other winners included Realtime Worlds' Crackdown, Thatgamecompany's Fl0w, Crytek's Crysis and Nintendo's The Legend of Zelda: Phantom Hourglass.

"The Game Developers Choice Awards stand out from other game industry prizes by being open to all games of a calendar year and by recognizing the individual developers behind each celebrated game," commented Jamil Moledina, executive director of the Game Developers Conference.
