When i was 4 and people adked me whated i wanted to do when i grew up, my answer was “make planes.” I got a master’s in Aeronautics and Astronautics and a PhD in Mechanical engineering. At work i function as an applied mathematician (algorithms, modelling, uncertainty quantification, geolocation, that sort of thing, a lot of it related to satellites). I enjoy building/designing things e.g. optimized characters or house rules (the nubian design collective’s whole vehicle crafting handbook) and even my own homebrew system (3D). Yeah im the math nerd who grew up got the job and the girl of his dreams. And we now have 3 kids under 5 which means i have no time for actual gaming any more and extremely limited time for designing rpg rules for others to enjoy.
