@aras yes, we had a tech report with our initial findings and a ton of folks reported some great precedents in old games. We knew of all the academic literature, but game developers just use them and often not even report. :)
The coolest example was this old Star Trek game and the first Unreal, we had no idea! This helped us a lot to contextualize our research. :)
Game developers, please report your findings and even "hacks"! :)
