I was aware of the patent, and agree i think its overly narrow and you could get around it easily. I think the reason we haven't seen it or something like it in another game (or i haven't but someone pleeeease id love to hear systems like it), is less because its not useful, or maybe its not useful as a plug and play because the only reason it works is because of the super exhaustive care taken on tuning its parameters and giving it enough variety to make it interesting to play.

Kinda like the dialogue/story paths in something like hades, where IIRC they made a whole system to manage it, but the reality is that system only matters when the tree is suuuuuuuuper complex. or maybe it was disco elysium, or both ...
