Before you could find nWoD in stores, I did a rules hack to old World of Darkness. So basically before new World of Darkness rules were available, I did a rules hack/house rule similar to it.
Basically I thought, that for storytelling game fighting should be a bit faster. I mean, there are almost always three dicepool rolls involved:
1. Roll attribute + skill dicepool to determine did you hit or miss
2. Roll damage, what is weapon damage + successes from previous roll after first
3. Opponent rolls stamina as soak
4. Decrease successes of stamina roll to determine damage dealt
There are three rolls to determine did attack inflict wounds. I thought, it might be done easier.
First I thought, what if you decrease opponents stamina from your attack dice pool and the successes are damage. I found out when testing this, that damage was dealt more than previously. Problem was a target number of 6. So I tested with higher target numbers 7, 8 and 9 and found that with target number of 8 you got similar results as several rolls.
So, now I had one roll to determine did character hit, and how much damage was dealt.
I also like exploding dice (get highest number from a die, roll again) but was not satisfied on how it was dealt in oWoD. If you had specialization in skill, you could roll 10's again when tried a task with that specialization.
So I modded it this way:
Everytime you score a 10, roll again for possible bonus successes.
Specialization in skill means that you get +1 to dice pool if you try a task involving that specialization.
Those rules I houseruled waaaay before year 2004. But actually I never used first simplier combat rules because I felt that it was too much hack for the rules. Now was thinking, that maybe I should after all.
