A simple mod where the base quality levels are stronger, but harder to reach. Based a condensed version of the additional quality level mods.

I feel like for buildings, you move through the quality levels too fast and max out, even with the smaller bases I tend to play with. Originally I was interested in the additional qualities mods, but those just add repetitive layers that I don't feel like really adds much to the experience. They're kind of fun once but then it wears off, and not for regular use. I felt like the transcendent quality mod was close, but not quite what I was looking for.

So the steeper quality mod was born. Upgrading in quality is now harder the higher you go. The chance is lowered to 75% of normal for uncommon to rare, 50% for rare to epic, and 25% from epic to legendary. The other part was to have each quality level feel like a good step up instead of a minor upgrade. The quality level progression goes from 1, 2, 3, 5 to 1, 3, 6, 10. This ensures that every quality level feels like a good boost from the level before, increasing the bonus from the previous level by roughly 45% (except normal to uncommon, which is kind of just an entry point and because I didn't want to change its odds below normal). The stronger modules partially offset the lowered odds to go up a quality level. This progression feels more rewarding than the base progression, where rare to epic is the weakest % boost at only 19% stronger.

Note that this works well for factories, but would be quite overpowered for personal equipment and combat unless you're playing with a mod to make enemies significantly stronger in late game. Something like entrenched enemies that raises the quality level of biters would probably keep it more fair. Unfortunately you can't tweak those values separately, at this point at least.

This mod might not appeal to everyone, but I thought I'd throw it out there for people that think the same as me. Yes, you could create this mod in one of the mods that lets you manually tweak quality, but it might not occur to someone to do so. Also as of 1.0.1 you can edit the values yourself if want to experiment, or to help bridge the difference between quality in space age and quality without it.

So this mod is likely for people that want quality to feel like a bigger upgrade and need a little more effort to climb, and further incentivize devoting resources to climb it, and people that don't want to be bogged down with an overload of different quality types to manage.

This mod probably isn't as good for people who want to produce entirely legendary items, or people that wait until the late game to even touch quality when it's climbed with virtually no effort, or who want the additional challenge of building a base that can deal with so many types of qualities simultaneously.
