I’ll credit Quake for helping/exposing me to networking, filesystems, and shaders at a young age - one of the few games that truly encouraged (à la Quake Console) making modifications and setting booleans to configure settings. That was enough at the time to encourage me to teach myself JavaScript, PHP, and SQL - as I had some web projects in mind that I needed to execute on for the Quake clan I founded. This later became freelance, which later became a side gig through school. I was also grateful for the various sponsorships and earnings at the time so I could keep my equipment up to date and pay for storage.
Fast forward a bit, and I’ve mostly worked in SecEng at a number of great companies, most of them popular FinTech and FAANGs..I’m extremely fortunate and have been able to work at all my favorite companies. I’d like to think at minimum, Quake prepared me professionally be meticulous in my craft, study human pattern behaviors, and know when to take risk.
Lastly, I can (hopefully) better answer your question in a few years as I am just now working through switching careers completely to become a Motion Designer. There’s something extremely appealing to me to be able to work with 3D + Engineering, while still being able to solve problems AND feel creative at the same time.
..maybe this desire stems from Quake, maybe not. Either way, Quake has a permanent location in my heart.
One thing to keep in mind is a lot of mods were frowned upon or flat out not allow at all, especially as you can imagine with playing competitive. Once PunkBuster did finally get release for Q3, there was also a bit of hesitation from ranked players on making any non-typical modifications to the game out of fear of being banned. That said, aimbot was a huge issue with Q3 and rarely did I witness PunkBuster do its job.
iD tends to be very tight lipped about things from my limited interactions with them, even in person at Quake Cons..but I do know they were all hanging out on the same forums and places the players were at - so my hunch is they were aware of it.
Most of the popular mods were rolled in as game modes though.
As a note, I recently played for the first time in over 10 years. I got banned until 2029 from the main RA3 sever most people play on because I achieved 60%+ accuracy in a match and people thought I was cheating.
I also got the aim bot achievement from Steam as a result, which only 3.6% of other players have.
Back in the day I had a very tiny sponsorship with HyperGlide where I tested their products before the launch. They are credited for making the first hard surface mouse pad. I only received mouse pads, but I was happy to receive this.
I am a former Quake 3 champion, have a lot of experience dealing with Quake 3 servers :)
