I make the Life Simulator Engine. It's not just for tabletop, but I think it might be useful to game masters who want to simulate something that's a little much to do with dice. Take mass combat, for instance; sure, there are many systems that let you abstract that, but suppose you don't want to, and would like to game out exactly what everyone's doing on the field until the moment the players decide how their characters act. Then, input that as a change to the simulation...and set it back to simulating on its own.
That's a lot of work, though, and I'd like to get something done in time for this jam. So I'll be adding features that make it more convenient to use Lisien in tandem with a tabletop system, not as a virtual tabletop per se, but a database for the game master to use in tracking the game state, and which can take over procedural elements if the GM wants. I may even be able to save them having to write actual code, if I know enough about what they'll need.
I happen to be interested in the game Reign, so I think I'll make a One-Roll Engine die roller for Lisien, and then try using it to automate some smallish political feud from the examples in those books. It could run between sessions, and set up the plot for the next one. But, if you're a game master, and you think Lisien could help you run your game, tell me how, and I'll see what I can do.
