Thanks for the help. I guess what triggered my concern was reading the a couple of published scenarios, most of them have a number of combat encounters scattered along the way. Compared to my game they seem to have angry farmers, crazed sheriffs, several cultists, thugs, magic users and such, which is a bit too much if you ask me. But I guess I can grab a couple of guys from the tainted town I created to follow my players, perhaps trying to disrupt the investigation. That would provide me with a possible chase, a brawl and a likely prisoner to compromise for the clues which my guys would definitely miss : )
I also have a question about the interviews; I have several people with important information to give, but first they need to be asked about a precise topic. I cannot see how a roll would affect this interview since all it takes is to be know what to inquire for, and if the player cannot come up with the topic, no roll should be able help her to get that information. Is there a mechanic for that? Or do you just provide the question if, say, a player succeeds with a charm roll or something?
