Where characters don't have differences in ability? Could you give me an example of such a system?
d02. Every time a challenge is encountered, flip a coin.
A different sort of puzzle is presented by something like Fantasy Craft, in which all NPCs are scaled automatically. The remaining differences (the number and type and potency of special traits they have) mean that NPCs are, by default, about 90% tailored and 10% pre-done, whatever your intentions.
Another sort of problem: Marvel Super-Heroes. Since characters are essentially static, is it possible to meaningfully categorize those encounters as status quo or tailored?
