There is also a lot of interesting UI and general programming info, probably worth a read even if you aren't interested in games. Chaim Gingold also has a lot of good info relevant directly to FOC. His Sim City dissertation is really good https://pqdtopen.proquest.com/doc/1806122688.html?FMT=ABS

I found Chaim’s masters thesis to have a lot of interesting interface design thoughts as well http://www.levitylab.com/cog/writing/thesis/
