Hey! First off, thanks for the wonderful mod. Second, thanks for the wonderful mod. : P
Now, I could be mistaken, but I believe it's this mod that changes PP so that you get a -2 rep for each failed attempt. While I think rep loss is better than NPCs simply turning red, and their neighbors, and the whole town, and... you having to reload or your game is broken, I think the rep loss is too much.
Killing a person only costs you 4 rep, so it seems odd that stealing is considered almost as bad. It's odder that if you keep failing, you can be hated MORE than a murderer. In fact, you can easily go from max rep to zero rep by failing over and over on the same person.
Given how much it costs to pay off the guards, given how much it costs to raise rep in temples, and given how LITTLE you get from the average person, PP doesn't seem to be worth it. I think there should absolutely be a cap on rep loss.
My ideal rule would be to give a max penalty of -1 rep, per person. No matter how much you rob Suzy, you'll only get -1 rep. You can still get -1 rep from failing to rob Steve, and Pedro, and beggar, but each person can only damage your reputation so much. Even -1 is high, again compared to how much it costs to raise rep, but at least it's something.
Or perhaps, allow a lot more chances to talk your way out of blame. In any case, I wanted to make the suggestion, if you implement it or not, is of course up to you.
