Why don't 3e and 4e use percentile dice for skills?

[QUOTE="ggroy, post: 5030878, member: 83805"] I would agree in the case of adventure type games where rolls of critical successes and failures are not a major thing. Cases I can think of offhand where percentile dice systems can have a big difference from d20 is where criticals are a major thing, such as in a superhero type game where there's several different degrees of criticality. For example, critical successes can be incorporated into low rolls of 1, 2, 3, etc ... while failures are incorporated into high rolls of 100, 99, 98, etc ... where the closer to 1 or 100 the roll is, the more drastic the success or failure is respectively. Another case could be where critical successes and failures are incorporated into "doubles" rolls of 11, 22, ...., 88, 99, 100. Rolling "doubles" over the "DC" percentage is a critical failure, while rolling "doubles" under the "DC" percentage is a critical success. The likelihood of rolling a critical failure or success is dependent on the "DC" percentage for a success. For example, a "DC" percentage of 85% for success has 3 "doubles" for a critical failure while it has 7 "doubles" for a critical success. A "DC" percentage of 30% for success has 8 "doubles" for a critical failure, while it has 2 "doubles" for a critical success. [/QUOTE]
