I like the nostalgia of the name, and the system sounds good.

I'd still like to be able to sell Materia equipment. Making it unsellable doesn't appeal to me as a crafter. But I can understand why they would do that. My other thought is I hope that we can remove materia from a piece of gear, for example, later down the line you get a better piece of materia, but you've used up all your slots, I think you should be able to change out the current set, so you aren't stuck.

However, this does sound like it's going to be a good system to add into the game.
