More and more, I'm really like systems where PCs do all the rolling in combat. For example, in ICONS, attacking PCs make a roll vs. an NPC's defense rating, and defending PCs make a roll vs. an NPC's attacking rating. The Ubiquity system can essentially do the same thing, as long as you "take the average" for the NPCs' attack and defense rolls. I like this because it gives the PCs more to do and me, as GM, less to do.
I was wondering about something similar for BRP: I'd like my players to do all the rolling in combat. To that end, I was thinking of stat-ing NPCs in such a way that their defense skills are just negative modifiers to the PCs' attack rolls, and that their attack skills are just negative modifiers to the PC's defensive rolls. There's already some precedent to this in the BGB in the form of the defense skill, so it's not much of a stretch.
So, if I go this way, I need to think about what values to assign, perhaps in terms of how I would convert NPCs in published adventures. I was thinking 1/5. For example, if an NPC had a 50% Dodge skill, that would translate as a -10% penalty to the PC's attack roll; if the NPC had a 50% attack skill, that would translate to a -10% to the PC's defense roll.
Thoughts about that? Again, not if you agree or disagree philosophically; just whether the math seems reasonable, IF I decide to give this a try ...
Thanks in advance!
