Have you had any thought on doing a progressive quality mod or addon? I think it would stay balanced if you kept it at the doubling with starting at 0.01% or something incredibly low increasing by a 0.01%.

I haven't really thought too much about it yet. I've got some ideas for a kind of game mode where the player is extremely limited in the amount of machines they have access to, but they can level them up somehow, but I haven't given it a ton of thought. Quality is in the same boat, I haven't thought too much about it, but I think there's a similar progressing thing there as well. If you have suggestions I'm interested in hearing them!
