I'd love some advice from some experienced GMs on tips for running a successful adventure path.
I have several years experience running Society-type games under Living Greyhawk 3.5 for a home group, as well as about a year's worth of experience running Pathfinder Society home games, but at Christmas I started running a Kingmaker campaign for a group of 4-7 mostly novice players. This is something completely new to me and I'm finding the long term focus and broad boundaries quite a challenge to my developing skills - the whole experience is for me both incredibly freeing and nerve-wracking!
One of the main challenges that I see myself having to overcome in this campaign is my tendency to want to "save" my PCs. In my GM career thus far, I have yet to kill a PC, though in reality I can think of probably 3 or 4 situations where I definitely should have. I'd appreciate some advice on how to embrace lethality in a long running campaign, preferably without alienating my players. I want the world to seem "real" to them, and death is certainly part of the real world, but I find myself balking when it comes too close...
Case in point:
Also, with so many of my players being brand new to Pathfinder and tabletop roleplaying, I'm not sure if I can trust them enough to know enough about the rules to be able to save themselves!! I like to employ Knowledge checks to allow their characters to become more informed about possible threats, but how far should I take this, especially when it comes to knowing the rules behind battle tactics? Any resources or suggestions that have worked for fellow GMs out there would be greatly appreciated, especially when it comes to dealing with novice players!
