Thanks, Gilgamesh, Demoniac, Coze, and everyone else who commented on this thread!
@coze, I didn't talk to her about SSI stuff. I would love to talk to those guys, though. I did interview Keith Brors of SSI a few years ago, but haven't been able to get back in touch with him. We chatted on the phone for an hour or so about the gold box engine.
As you might know, I've been having some problems with YouTube recently and may not be able to continue the series in its present form. I'm not sure what the future holds, though.
