via Winchell Chung. I feel like I’ve been working toward something like this for a while. The next trick is, how to make an actual game system out of it.

My experience in trying to design such systems is that the main problem is to make it not boring. It has to be a lot more interesting than a quick rock, paper, scissors.

I have some more notes about the triangular graph here

This is focused on warship design, but you can adapt it to an RPG.
Ken Burnside adapted it for five variables

A roll under percentile system? Seems the obvious solution.
Roll for attack (roll under weapons)
If succesful: damage is dealt to enemy ship. Colour in triangles equal to amount the roll succeeded by, divided by 10. Any coloured in triangle in a particular area (defense, propulsion, weapons) reduces that area’s effectiveness by 10%.
Propulsion is used for initiative and gaining positioning advantage.
