Factorio Friday Facts #375: Every item, entity, and equipment has five possible qualities now, and each quality tier gives an improved bonus value

Honestly pretty excited for the gameplay implications here, as it adds another tier of refinement on top of what's already there as well as addresses the problem of endgame builds being kind of painful to slap together. Here your reward for grinding up to legendary is that you get to build a smaller footprint out of more expensive materials, which will improve the endgame slog substantially.

Similarly, I think the idea of quality variation introduces some pretty interesting tools for modders. Going to be exciting to see what they come up with as an extension of this new framework.
