Yes it was a fun episode to listen to. That couch has a lot loose change in its depths.
So on to my Unconventional Warfare
This is a war fought not with swords or guns. It's a war fought between two alien races over the fate of Humanity. It's hard to say if one is evil and the other is good. It's best to say that one represents The Galactic Federation of Worlds, the other, The Unaligned Free Worlds. We can call them Purple and Green. They manipulate events on Earth, with the ultimate goal of having humanity join their side. Yes, the machinations can lead to wars and peace, and happy endings and unmitigated suffering. In their eyes, the ends justify the means.
I would use Microscope
for this game. Yes, it would be GMless, but that makes it even better. A minimum of three players: Purple, Green, Humanity. If you have more players, add extra humans first unless you have a multiple of 3: 5 players, Purple, Green, 3x Human. With multiple of three, you'd have 2x Purple, 2x Green, and 2x Human.
If you're familiar with Microscope, you define the start and end points. In this variant, you have one start point, but three potential end points: Purple win, Green win, Humanity does it own thing. The latter is undefined, as it will come out in play.
In addition, events are no longer "light" or "dark", they are now "purple", "green", and "mauve". That is, a Purple win, a Green win, and neither win. These wins are decided by consensus, so there will be lots of discussion over how the event was resolved.
The time period will cover centuries if not millennia, the whole course of Human history, and the interventions of the Alien races coloring them.
To determine who "wins" count up the number of "purple", "green", and "mauve" results for all events. Whichever is 25% more than the others, that one is a winner. If there is no clear winner, then it is definitely a human win, but not a major one. A mauve win, would be a definite human win, a statistical tie is just humanity eking out a place for itself, outside of either Purple's and Green's domination.
Now, it's possible to have a statistical tie between mauve and another color: If there is only a 5% difference between Green and Mauve, but a 20% average difference with Purple, then it would be Humanity and the UFW joining forces against the GFW. This sort of reminds me of Alan Dean Foster's short story "With friends like these..."
. I'm of a mind that this pairing might be one the UFW may regret.
