The way RPGs use “experience” as an abstraction of the idea of getting better at things gets weird in games where you can get experience for non-combat things.
Like, this is a world where you can raise chickens so much that you learn to cast fireball.
Something about the experience (no pun intended) of raising chickens; feeding them, cleaning out their coop, collecting the eggs?
That somehow taught you important things about arcane evocation
As a pattern recognition program who has managed to apply input from datasets on macrame and shibari to the installation of a monitor for my LaserDisc player, I very much approve
All things are connected and if you pattern-recognize well enough you can use ANY experience for ANYTHING
