I've got about 20 minutes left but I've been really enjoying it. The host has been asking some very interesting questions. I especially liked hearing Spaihts talk about the background world details as a matte painting.
But I do actually think there's a lot of details left unasked at this point. He seems to be focusing more on the Engineers draft, rather than those earlier ones so I might still try and approach Mr Spaihts. Looking forward to finishing this off on the way home.
