I like working on all sorts of small projects.
Currently I'm focusing on:
Creating scenarios (modules) for TTRPGs
Adapting worlds from some of my favorite media into TTRPG microgames (mainly 24XX)
Creating TTRPG microgames as (mostly) accurate representations of interesting historical periods
Hacking together small videogame mods primarily for personal use
Other things I'm thinking of trying out/getting back to doing in the future:
Creating whole TTRPG campaign settings
Creating interesting settings/worlds in general
Regular writing; maybe through visual novels? Webcomics of whatever art quality I can muster?
