I note you say the dice pool mechanic, as if it is singular. It isn't. There are many different dice-pool mechanics, and they aren't equivalent.
True. There are three main types of dicepool mechanics as far as I can tell.
1. D6-style: Roll a bunch of dice based on skill level
1, add them together, and try to get above a difficulty number.
2. World of Darkness-style: Roll a bunch of dice based on skill level, compare each separately against a difficulty number, and count how many succeeded.
3. Traveller 4-style: Roll a bunch of dice depending on difficulty, and compare to skill level.
1 For convenience's sake, I use the term "skill level" to include ability scores and similar things as well.
There are some other variants as well (such as roll a bunch of dice and compare the highest to a difficulty, and roll a bunch of dice and see how many match), but these are the main ones I've seen.
