Change the names of Quality tiers to anything you like.
Providing the player with new tools or adjusting the game interface, without fundamentally changing gameplay.
I think you should depend on "quality" instead of "space-age" in the dependencies, so that people can use this if they're playing without space age.
Yeah I created it before I knew they were separate. I have an update ready but cant test any of it. Guess I might as well push it out :)
