If any developers are still looking for features for DA or later, how feasible would it be to extract selected calculations from the code and make them editable in a configuration file? I know that Diablo II did some of this in the 1.10 patch, where the arithmetic was expressed as a set of variables in text format.
I'm thinking that if this were possible, it would make alternate-world mods much better, instead of just being a set of logos and custom stats. If the developers wanted to go all-out, they could even separate the formulas by race, so that each side would be it's own unique, configurable game.
