Hello. After hearing a lot of discussion on the use of the d20 system, I would like to offer my two cents. Personally, I think the d20 system is just plain silly. Maybe I don't understand it that much. It has the advantage of being simple, but the biggest problem I have with it is that it is hard to conceptualize, as compared to a d100 system. Let me explain. With a d100 system (which DR incorporates somewhat) I can easily picture the chances of a success roll in my head. If I have to get a 40 or above on the roll, I know I have a 60% chance of succeeding. That's easy to grasp; the human mind works in well in multiples of 10. With a d20 system, you add the roll of a d20 to your skill level, and try to beat the difficulty level. But what does it mean? My mind doesn't work in units of 20, and there's no easy way to explain the results mathematically Furthermore, the use of a d20 is not necessary. Why not use a d6, a d8, or a d12? It seems arbitrary to choose one die over another in this kind of system. What do y'all think? - steve brown S.D.G.
