I would actually like to see more gaming articles on HN, as long as they have as technical slant like this article does. Video games are a huge avenue for computational exploration, with many difficult research problems in graphics, AI, physics, optimization, systems, high-performance computing, and even cognition modeling.

Of course, I'm certainly biased since I'm attending the Foundations of Digital Games [1] conference this week.
