Also of note, San Diego Game Firm Rockstar took Game of the Year and three other categories in the GDC, winning four awards altogether. Go SoCal.

Founder of Lionhead Studios Peter Moylneux walked away with the Lifetime Achievement Award, for his involvement and creation of games such as Fable, Black & White, and that favorite classic, Populous:

He's the guy that created the first Populous? "Lifetime" Achievement indeed!
And let's not forget that Yu Suzuki won the Pioneer Award for inventing an entire genre with Virtua Fighter. My favorite part about VF was the absurdly unnecessarily high jump attack. Oh, and the giant pixellated muscles. And this guy:

Ah, memories.
