An expansion to the quality system in Factorio.
Small changes concerning balance, gameplay, or graphics.
How about splitting the quality tiers added by this mod into separate research projects and unlocking them after the Promethium Science Pack?
Worth making as a setting. Will explore it in my freetime.
Hey i would appreciate this too, if you still have it on your list :) Unfortunate i'm too dumb to do it myself :D No stress if you find time, but great mod so far ^^
