Towards the end of the article I mention "some of us have been working out the rule set for how you can link loops into a larger network of problems for literally over twenty years."

That is referencing the "game grammar" effort undertaken by myself, Dan Cook, Stephane Bura, Joris Dormans, and many others. It is very specifically about arriving at a notation system for gameplay logic.

The original talk from 2005 is here: https://www.raphkoster.com/games/presentations/a-grammar-of-...

The principles in this talk went on to be used by the field of computational modeling of games, AI game generators, and also used in training AI game players.
