I'm always curious about the lack of TDD in game dev. Several of the errors discussed in the forums sound like exactly the kind that TDD would make it very hard to make. It's not my business to tell other people how to code, no doubt they operate under constraints I'm not aware of. I'm just curious to hear other people's thoughts, is all. I often hear that people think automated testing of games is harder than of other software. But whenever I try to understand why people think that, the reasons they give are just a subset of the same reasons that testing-done-naively can be hard in any domain. Please educate me if you think otherwise, I'm just trying to discuss, not criticise. :-)
