Numenera?

General query. Anyone with thoughts, experience, or information is hereby encouraged to share. I'm off work today and tomorrow and ended up and the local Books-A-Million. While there I saw Numenera. I thought it looked intriguing, and not having a lot of time to sit down with it and a hot cup of coffee (much as I would have liked), I came home and began furiously educating myself. Up to that point, it was an interest. Then, I came upon this passage, I believe from the introduction:

Then, I was lying in bed one night about a year ago, and in my mind’s eye I saw two figures pulling tattered cloaks around themselves to ward off the chill as they walked. The two trudged across a grey landscape, wary with each step. And as this scene receded, I saw that the terrain they crossed was a massive gear, and the landscape was in fact an unbelievably huge and ancient machine. The key to this scene, I realized, was that the figures were in no way part of this terrain—perhaps they didn’t even understand the concept of the machine—but they were accustomed to it. It was a part of the world they lived in as much as mountains, rivers, and forests are a part of ours.

I feel like I can see that, too, and I too find it strongly compelling. Now I feel driven to run down a great sci-fi/fantasy setting. So, tell me of Numenera, or failing that, your choice for that type of game/setting. I'm mainly interested in all-in-one things, so something like Chronicles of Future Earth aren't really what I'm looking for.

Any advice or thoughts, or pointers to things I may not know about, are heartily appreciated.
