Didn't know they were produced in such large numbers. Considering they were made so numerously, I can't seem to find a picture of a single example online of other similar burns. I'd love to see other pre-production discs released by Microsoft, any chance you could snap a picture of some of the many that you own?
Thanks for the info as well, nice to know that it does indeed appear to be a pre-production copy of The Neverhood.
