Quote from: Phillip;645988Try just thinking of what probabilities you want for things, saving minutia of what dice to use until you've got that settled (if it even turns out to make a difference at all).

I 'm not sure how to work that out.

I was assuming Attribute + Skill with each going up to 5, so 2-10.

That seems a reasonable width, not too much so the players can't see the progression of their character, but not too small so everyone is the same.

What I mean is, think first in terms of the phenomenon you want to model.

For example, suppose I want to have a Strength factor set a weight that can be lifted easily (twice as much to the waist as above the head), with twice as much being a chancy attempt.

One way to do that is with weight factors that double every 5 points: say, 100kg at 10, 200kg at 15, 400kg at 20.

A d6-d6 (higher minus lower) roll could be used, requiring a sum of that and the applicable Strength factor at least equal to the weight factor involved.

The number plugged in from the strength side and then modified for circumstance could be identical with the basic Strength score, but need not be. Perhaps I will find it more convenient for other purposes to have the basic Strength score be on a different scale, and map it to a table of weight-lifting factors.
