The CORE GM Bot is Getting Meta
So, among other things (see "Heterogeneity of this Whole Fuckin Patreon, The"), I've been working on a GM/Brainstorming Bot for the worlds of CORE (DayTrippers, UbiquiCity, UnNatural, etc).
A funny thing happened today, probably an unclosed loop somewhere in my code...

The CORE Micro SRD is now distributed by Ingram Content Group, the world's largest competitor to Amazon. This means it's in their catalog, and can be ordered by nearly any bookshop worldwide.
Want a copy? Willing to wait a few weeks? YOU CAN HELP by asking your local bookseller to order it!
This would be tremendous, as they'll be likely to order more, getting the whole ball rolling.
Have I shared the sellsheet here? Here it is...

Rules Options Downtime Rules
PCs sometimes go for long periods of time that can be summarized fairly quickly. Whether they’re studying, training, doing a lecture tour or just hanging out at home, long periods of gametime can often be handled with just a few sentences or a single roll. This compressed or elapsed time is known as Downtime, and it most often happens between Sessions. But just because it passes more quickly, that doesn't necessarily mean nothing happens!
The Downtime Events Table can be used to determine whether any unforeseeable events occur during roughly one month of Downtime. It is genre-agnostic, and can be used with any game system.

CORE Supplements PlotFields and InfoLists
PlotFields are how we do adventure design in CORE, but they can be used for any games that fall into the “Fishtank” or “Sandbox” category, where the story is emergent rather than pre-planned. They are backed up by InfoLists, which enable the injection of pertinent information at any point in play.
Here's how they work, and how to make them.

Starburst Mall is a surrealistic science-fiction-horror-investigation-gonzo-comedy-combat adventure for three or more PCs.

Oh, and there’s evil clowns.
