Interesting, reminds me a bit of a game chef entrant to some extent. I have a few questions that get in the way of playability, but maybe I'm misinterpreting something.

An action can't be preformed with an attribute at zero - yet they are raised by use. (Does it have to be a successful use?) Are these changed by the actions of creatures, or else how do you get an initial rating in the control/destroy scores?

Presumably places are created the same way as other entities?

Now its probably more my style of play, but the lack of a defined goal seems to stand out.

One element you might want to add is a time limit to declarations. Since the effect is defined by the number of descriptors, some people might be inclined to take quite a while to ensure everything is phrased just so. Furthermore, this puts a bit more challenge into maintaining high level powers, or encourages a loss of power with a lack of forethought. If you recall old stories about 2 page descriptions for wish spells, then you know what I'm trying to prevent.

Its defiantly a unique game, it'll be fun to see where it goes.

There is a fine line between hobby and obsession. I seem to have lost sight of it some time ago.
