All assembling machines, furnaces and mining drills have a base quality, so you're forced to deal with qualities the entire game.
Small changes concerning balance, gameplay, or graphics.
Augmented or new ways of transporting materials - belts, inserters, pipes!
Mining drills only allow quality modules with this mod. Was kinda painful to not be able use the efficiency modules I made.
Aside from that I have been having a blast so far with this mod + another for more quality levels.
