Now try explaining in plain English, or simple math, how changes to TNs above 6 (and that's generally where the changes go in SR: up) affect the probability of achieving X successes with Y dice when X and Y also can change, depending on the circumstnances. Directly, yes, in the same way that load-bearing members made of stronger materials allow a structure to support more weight. Making a more precise statement as to what that relationship is, however, requires a lot of engineering experience and calculus chops. My point is merely that SR's system makes it very, very difficult to figure out on the fly what a character's chance of accomplishing X task given Y dice, Z number of required successes, p target number, and r mods (especially the mods!). The one-die-plus-applicable-mods structure of d20 makes doing this a snap, and does away with SR's probability structure, which is highly disjunctive due to the exploding dice roll rule. Note, for example, that a +3 to the TN has a vastly different effect on probability if the initial TN is 2, compared to if it is 5. Or the fact that 6 and 7, 12 and 13, etc. are equally easy results to roll. I am merely explaining why my players have issues with SR, not whether the system is "better" or "worse" than d20.Actually, it does model success-based results in a more predictable and cleaner manner. But that's just IMHO...</blockquote>
