This is reprint of the feature article I did for Game Developer Magazine for their August 2012 issue. This is slightly longer than what appeared in the magazine. (They also had a lot of cool pictures of Mexican food.)
Thought this would be relevant to put here. This is a repost of the column I wrote for Game Developer Magazine's monthly "Inner Product" column for the January 2011 issue. I had forgotten that I had permission to post it 3 months after it appeared. *shrug*
Anyway, there's a ton of good information in it, so it might help out a lot of people here.
