...To the point that any action actually based on the four attributes in Nobilis is considered miraculous, and simply won't fail unless countered by another miracle of equal power: a character may perform one of those per turn, along with one mundane action such as jogging around or debating in a regular fashion. One of the attribute ratings, Aspect, covers by itself all the physical, mental and social activities that people generally are capable of, as a kind of a measure for baseline competence and not unlike all the attributes in most other RPGs rolled together, although those abilities can still be fine-tuned further by picking appropriate Gifts and Handicaps. The finest feats performed by the most talented mortals correspond to the lowest levels of Aspect: winning a gold medal at the Olympics would have the difficulty level of 2, for instance, which renders it completely effortless for any Noble whose own Aspect attribute (ranging from zero to five) is at least equal to that. And something that anyone at all might do with a bit of luck? That's difficulty 0, and not even worth resolving mechanically unless the player wishes to ensure that there's no chance of failure whatsoever. No Noble slips on an icy street unless it's either a deliberately taken risk on their part or a sign of some supernatural enemy moving against them.The game is not focused on the details of mundane action.
Here you go. And while you're over at that 1KM1KT site, why not take a look at Sufficiently Advanced, a Culture-style science fiction game released under Creative Commons?Other than that, I fondly remember reading a 24-hour-RPG-contest entry called Silent Archea; I can't find it on the net anymore, though.
