Hi man, I have an idea to pitch to you since ur such an artsy game maker.

The purpose of a game system, in general, is to be fun and engaging. This is achieved, in this context generally, when a person impresses himself with his intelligence, creativity and/or skill and feels a sense of growth (with respect to those same faculties).

What a person should not be made to engage in is self-control in not breaking out of the rules of the system itself, because that destroys engagement in the system and therefor the fun of it.
(this could actually be an interesting idea to design one of those ‘artsy’ games around, I’ll pitch it to the Return of the Obra Dinn guy, maybe he can prove that it’s actually the most fun).
