I have an almost encyclopedic knowledge of fish from the atlantic basin, specifically in and around the south east US and Carribean.
It freaks people out sometimes when I just start reciting fish facts whenever the rare occasion this comes up.
It's from me living partially on a boat as a child and tearing through books about fish while dreaming of being a marine biologist until the cold hard reality of for-profit education hit me in my early adulthood.
What are your weird topics and skills?
If you do work on board games please do play test and look how long people need from 0 to play and how nice the specific mechanics for given problems are. Eg at pen and paper role playing you don't want to have complicated dice rolls that take a while to roll and to read and to interpret.
