Damion Schubert's blog
This is as good a moment as any to link to Damion Schubert's blog Zen Of Design, seeing how he's just linked to me and added a comment to the "On Academia" post.
I first met Damion at this year's GDC, when I went up to him, introduced myself, and told him we'd both worked on the same project. Which is kind of strange as we'd never met before, but then he did some work on Highlander Online after I had already left Kalisto Entertainment.
I haven't taken a longer look at his blog yet, but it looks like there's a lot of stuff there - it goes back to June 2002, which has to make it one of the oldest blogs by a game developers out there.
