It's an opinion comment on the internet, not a dissertation, but I base it on talking with one person who worked at valve hardware for a time and public information from the ex campo santo people's blogs and things. I could be very wrong and would love to hear from them, but I have a strong "what could have been" for 'valley of the gods.'.

Thanks for explaining. You made a claim outside of your personal experience, so expect to be asked to back it up. I’m not sure why you’re surprised.
