You really need an "other" response for the poll. I didn't vote as there wasn't an other option.

Depending on your definition, I used to run combat simulations for the military back before online MMO's became a thing. I didn't write the code myself, but I worked with the programmers in getting their code to work for the combat sims that I ran.

I started my professional life as an Electronics Tech, and then moved on to working as a systems administrator and Infrastructure Hardware Engineer before going to work for two major hardware vendors. So while I have not worked directly for a gaming company (If you don't count Combat Sims), I worked in the industry as a vendor that supported the hardware that several gaming companies used.

I chose that I have great knowledge and not working in the industry, even tho I worked for both Electronic Arts and Sony Computer Entertainment America for many years even though I am currently disabled now and can't work any more.
