The CWAL Rubber Room
"Paradox is a two-foot-tall mushroom who has more charm than all of humanity. Combined."
I think maybe XII's license board accomplished a lot of the good things you could do with this, but was a lot less confusing?
X was the first FF a skill tree though (I think?), so this was sort of new ground.
Also kind of neat that Salt & Sanctuary kind of took the sphere grid and simplified it a bit - just a multi-branched skill tree you can build on from any point you've unlocked without any of the "moving around" nonsense.
Anyway, it was also a really early era for fully voice-acted AAA games, especially for its length, so it's gonna get awkward!
