for a while it would have been the thickets campaign hexcrawl but im actually Doing The Thing now with that, so a few new ones:
a ruleset for playing mercenary companies, i have some basic ideas and id love having this in the chamber for a full game or metasystem to attach as needed to other games
a big Classic Traveller campaign. that game is cool as hell
a West Marches treatment of Thickets
i probably have more o these im not thinking of so ill append em if i remember
