Oh, and for those who don’t know what it is or how it worked take a look below, all your characters progressed along those various pathways one node at a time at each level buying new abilities and stat boosts from the node you were currently on, certain paths were essentially a class progression (one path would have a bunch of white magic spell unlocks and bonuses to magic and MP as your white mage/cleric progression, another one was focused on rogue abilities with speed and luck increases) but at certain points the paths crossed and you could start training them towards another class’s abilities and strengths.

But more seriously for a moment, I’d actually be really interested in seeing how 5e would get translated into this format, obviously you’d have class abilities as nodes but maybe even ASI, proficiencies, bonuses to certain checks and even spell slots.
