One variant, only slightly used:

1. Kept the attributes as-is with a single semi-exception. Why: The campaign hook was that the Gods of Ancient Babylon, or someone claiming to be them, return to earth right about now. (This is bad for Saddam and Richard Perle both, BTW.) So keeping the attributes made it easier to cost out the gods of ancient Babylon.

2. Most mortal characters would not have attributes at all. Instead they bought Gifts. (In fact, "Gifts" was to be the name of the campaign.) PCs were given ten points to spend, which will nicely equip you with a Justice-League-level character. Players _could_ buy attributes, but mostly didn't. Qualifiers:

a. It was announced that Spirit would not provide an auctoritas against anything but divine, supernatural action.
b. "Realm" was understood to mean "HQ" for super beings. You built a team headquarters using Realm points, same as in Nobilis. Actually, you don't even have to change anything. Try spec'ing out the Baxter Building and you'll see what I mean.
c. Fun thought: In Watchman, Ozymandias has a single point of Aspect.

3. Specific to our campaign: On the Where do superheroes come from? question, our answer was, "Somebody drew them." The PCs were frat brothers, one of whose friends was a cartoonist. In Babylonian mythology there exists the Tablet of Destinies, wherein what appears is true. Said cartoonist gets ahold of the Tablet of Destinies and draws his friends into the margin, in costumes, fighting crime. Before he dies.

4. Combat would work like it does in TGOP.

5. I decided against a more radical refiguring of the attributes. In that option, "Domain" would become "Metier" and could be used for things like "spider powers" and such. Also decided against splitting Aspect into the obvious Physical/Mental/Social components for the sake of the gods. We felt that we could have a very good superhero game with relatively few changes to the available rules.

6. Mind you, we felt we could have a very good _high-powered_ superhero game with minimal changes. I think you'd have to seriously reconsider our work if you wanted to do Marvel Knights stuff.

7. What about miracle points (renamed, informally, to Feat Points)? You start with zero and earn them in character creation by "overpaying" for Gifts. This includes, crucially, one-point gifts. Frex:

Gift costs out to -2 using the tables.
You pay 1 point, because you have to.
You earn 1 - (-2) = 3 miracle points.

You _would_ have the option of paying, say, 4 points for a 2 point gift and earning 2 miracle points that way, though in practice, people filled their MP pool from their one-point gifts. (As in TGOP, there is but a single pool for MPs.)

8. We were contemplating ways to replenish MPs more quickly than in default Nobilis. We were looking not only at restrictions, but at the possibility of Bond-based MP regeneration. (For the "mortal rules" I've been working on, Bonds work differently, though.)
