PallasRiotRules lite TTRPG systems are a scourge on the hobby and a fundamental misunderstanding of what games are. Trying to "streamline" games is largely a pathological drive from capitalist pressures, we can surely make the most efficient rules lite system ever by simply having everyone gather on a Friday, declare themselves heroic, and have a pizza. The point of a game isn't strictly the outcome, it's the process as well. It's primarily the process even!
Jackie@burnoutqueen Imo 3.X D&D is really a study in balancing interesting, robust mechanics with wanting to keep things accessible and generally does a pretty great job. Pathfinder does it a bit better than 3.5, but the whole 3.X cross compatibility makes that kind of a non-issue.
