I was thinking the same thing. Diplomacy is one of the best multiplayer games ever designed. This should be ideally suited for writing as a mobile app. I'd love to know if there any out there worth checking out.
Maybe, but the related startup idea that came to mind for me might seem
a bit odd; similar linguistic patters might exist in statements made by
startup founders and they might be indicative of success or failure. The
"excessive positivity" and "unnatural politeness" seen prior to betrayal
may also be present prior to startup failure.
The real problem with attempting to prove or disprove this conjecture
seems to be getting the needed data. It might be possible from public
statements from founders, but I think the more significant gems would
only be found private correspondence between the founders and investors
(or possibly customers). I sincerely doubt YC partners or VC's like Marc
Andreessen (@pmarca) and Ben Horowitz are going to let "just anyone" do
linguistic analysis against all of their private personal/business email
content.
