... it's a really good talk. And what it'll show you is when a serious game programmer actually needs to sit down and confront problems in reality how that leads them to conclusions that are different than the ideas behind these best practices.
Mike is the engine director at insomniac games, he works onn number of major, well-regarded, big, and complicated games, and has to solve problems in those games. so he is really worth paying attention to and worth taking seriously... So I encourage people to check out this talk and see what it says.
