NoNot generally incomplete. Always incomplete. To model something is to represent it incompletely.
And if your twice as efficient model has insufficient power to make any reliable predictions at all, can it even be called a model? Of course the general goal is approach 100% accuracy, and a possible goal is to remain within some predefined budget while doing so. That does not make 'smallness of model' a FEATURE. Sorry, this is simply untrue.It would be a worse simulation than one with the same predictive power that took half the time and energy. And one that did not finish processing until after the event being projected would be worthless (setting aside backcasting.)
If the models you have in mind couldn't be run at the game table, they are worthless in that context. Efficiency is at issue.
But the key part here is "insufficient power", and that's what we're really talking about here. The notion that I could predict weather with a 1D atmosphere model is ludicrous. The notion that I could predict political happenings and such from the World of Greyhawk Gazetteer is equally ridiculous in a similar way, they're simply not equipped with a representation of the necessary structure required to calculate anything at all.
They aren't 'functions' at all, they are simply labels people are attaching to decisions they made about the fiction which bear no resemblance to modeling or simulation whatsoever. This is not efficiency. You are constructing a sand castle here in which you mistake your sand for concrete, something it simply isn't. Saying you don't have any cement in it makes things 'more efficient' is utterly missing the point.It's right to specify "relevant" as not all data has equal impact on a model's success. Failure to include the most relevant data and dynamics can scupper a model no matter the thickness of its other data and dynamics.
So if by thinness you mean the bolded part, then with regard to imagined worlds enough of the most relevant data is in place. That was the poster's point.
Perhaps generally you are supposing that models of imagined worlds should play by the same rules as military, economic or scientific models of the real world. It's better to see them as comparatively simple functions. Efficiency is crucial as you normally want quick answers without too much pondering.
