This one is all in on the core roll mechanic: roll 3d6, add them up for the Total, use individual dice for the Effect. I go in pretty deep on the probabilities involved in variations on that (Advantage, Disadvantage, increase/decrease the die used, etc). This is the mechanic that I riff on in a bunch of different ways throughout the whole system.
In this one I get into the guts of what's going to be there: basically outlining the SRD's major sections and describing the kinds of stuff I get into in each. Some of the sections are full subsystems, some are less-mechanical linking ideas used to glue together other subsystems or provide structure to a game. (Also some of the sections listed there have outdated names! But most of them have roughly the same contents. Such is a system in development.) I also talk about the three games I'm planning for this system, and outlining as part of the SRD (which is like 50% example text by volume):
- Liminal Void: Regular people in space in the 23rd Century are thrust outside of normal society and must find a way to first survive, then thrive with their newly-acquired skills and spaceship. (Touchpoints: The Expanse, FTL, Alien/s, System Shock, Cowboy Bebop. Anything that has that kind of used-future in our solar system thing going on with a kind of survival-horror vibe to it, but less horror in the spooky sense and more the horror of living under the grind of capitalism.)
- Valiant Horizon: Heroic protagonists perform great deeds as they make a name for themselves. (Touchpoints: The dragon game you're almost certainly thinking of but mostly its 4th edition, JRPGs but especially Tales and Xenoblade.)
- Machinations of Court and Frame: Exceptional mecha pilots with mixed loyalties are thrust into proxy wars and byzantine power struggles between noble Houses. (Touchpoints: The mecha things I didn't rip off in APOCALYPSE FRAME but especially assorted Gundam/Battletech stuff. Thinking about Tactics Ogre/Final Fantasy Tactics/similar vibes too.)
...but I want to try out a few other ideas first with it to stretch the engine's legs a bit before I get into trying out anything mechanical for that.
The SRD's gonna be out soon (in PDF and free on my site) but I'm keeping a WIP thread here because I'll be posting about the systems I'm making with it too to keep them all in one thread, as well as anything I contribute back to the main system while developing them, that kind of thing.
