Regarding feedback - I think that flows directly from our ambition to put in consequences to the choices you make. In the presentation I gave in Leipzig there was the example of the the farmer who got betrayed by his wife. I ratted on her and as a result she ran off to her lover. When I would've gone to the blacksmith I'd have seen that she now lives with the blacksmith and is very angry at me. Likewise, her former husband is very sad though he is happy that I told him about it. Other choices would've had different consequences, which would've resulted in different feedback.
I would assume this would mean higher prices for the blacksmith's goods as well, but I guess it could go either way. His mistress is peaved at you, so he raises prices, or even refuses to do business with you. OR, he is happy that you spilled the beans and his lady is now with him all the time, so he favors you with lower prices. OR, he thinks he had a really good deal before, was getting his on the side without the hassles of a fulltime nag, and now takes out his biggest cleaver and wants to cut your head off!

Either way, it all sounds cool!
