I ran an in person (age of worms) game once upon a long time ago. It was left un-finished due to an interstate move, and I would like to see it brought to completion.
I do use the structured adventure path's plot points, but there is an entire world outside of what is presented in the magazine or what is presented in the original Greyhawk version.
This allows for the player(s) to apply more creative solutions to problems, that the original game designers had not thought of.
I also put more reality into the game, meaning that if you ask an NPC farmer how his crop is doing...you will get more then a 2 dimensional conversation.
...or if you do a bit of detailed research you may be able to find, and cut off a key resource the BBEG needs to complete his world ending goals, which means the BBEG has to come to you and fight on your turf where you have home court advantage and are the one that set the traps specifically with the BBEG and their minions in mind. (aka...completely derail the campaign in your benefit.)
I have no issue with players using any resource published by WOTC. But the same reality that I put into the world, I put into my interpretations of morality and ethics. So if you wish to use (the book of exalted deeds) your deeds must be exalted, when viewed both in and out of context.
if you want to use (book of vile darkness) or (exemplars of evil) or (villain design handbook)...well I think you can finish that thought...
I have a blank game I can use if you are interested in my concept. please ignore the epic 6 stuff...it is left over from a game that did not draw enough players.
