This is just like the conversation the other day. “I’ve been doing this for years.” The system Midian uses is directly taken from a 1st ed AD&D hack, with permission from its original designer, of course.

I’m probably jumping ahead a few days here, but was the class point buy version of Twentysiders crafted from breaking down various elements to skill equivalents? I cannot remember off the top of my head if this is already the case, but I can easily imagine a classless, levelless and xpless Twentysider distro that assigns points (each equal to one skill level) in place of the more finely granulated experience points, and uses these to purchase class & level elements in place of benchmarked class levels.
