Thanks for hosting this jam! It was my first attempt at making a TTRPG, and I don't think I would have taken the step otherwise.
Game: Machinae Deorum // The Gods' Machine
System: a novel system that uses tarot cards and regular playing cards
Theme: technology and interpersonal relationships of a dedicated inventor
Inspiration: American Gods by Neil Gaiman, Microscope by Lame Mage Productions
Goal: to send out my first attempt at a TTRPG and have it be at least playable (I think I succeded)
Etc: I tried to create a game for worldbuilding (one of my favorite things to do) which allowed players to create a technocratic or tech-heavy region for their games (my other passion). I tried to create plenty of bounded accuracy so that everyone has equal opportunity and reason to participate in roleplay and worldbuilding. Hope anyone who takes a look likes it!
