For fun, I’ve written some role-playing game adventures and designed a few games.
I’m making an expansion for Pelgrane Press’s space opera game Ashen Stars. The expansion enables you to play criminals uncovering secrets in a gritty space opera setting. It will be available from DriveThru RPG this fall.
I also wrote “Apex of Life” for Trail of Cthulhu, but it’s unpublished.
Back before Flash died, I wrote Daedalus, a fast-paced 2D race/maze-building game.
Finally, here are a couple chess variants: Zombie Chess and Alien Chess.
