This is an incredible collection and I'm very impressed by the research folder and the discovery of all of these.
I remember being amazed by the Reaper Bot and how smart it seemed, probably a result of how novel it was compared to other bots of the time. I liked UT even more than Quake though, and I thought it was cool that Epic offered Steve Polge a job based off of it.
Imagine having an 1x1 competition between them all and to see who wins, streaming in real time and with an AI narrator.
There's alot of neat Quake stuff on Github. Another repo of interest may be this one: https://github.com/SpiritQuaddicted/quake-code-archives -- I have a local copy of tons of RuneScape code: server implementations, clients, bots, etc. May need to get it presentable and posted up sometime.
