I see there are some homebrew modules out there that add spellcrafting but they’re more or less point buy systems.
I could kind of see it as I think you’re describing, in that you make a spell with a bunch of spell symbols/glyphs that modify it, but each one of those cost components.
Hmm this is worth scheming on.
The unfortunate truth is there are likely a lot of very talented developers at most big studios who ultimately don’t have a say on what goes into the game.
Many don’t turn around and try making a start-up game though, most just burn out of the industry forever.
