Hmm... Let's see here:
Shigeru Miyamoto - For creating Mario, The Legend of Zelda and other invaluable Nintendo properties.
Chris Seavor - For leading the Conker's Bad Fur Day development, among other feats.
Jason Jones - For creating Bungie and playing a huge role in their game development.
Robin Beinland - For creating the, by far, best video game music on the planet. Not a day goes by without a Banjo-Kazooie/Goldeneye/Perfect Dark/Diddy Kong Racing song randomly popping up in my head.
