So, it's a simple question. So far since the return of the guild, I've only had one RP I participated die, and that was before it started.

So I offer the question to ALL forumgoers, what kills it, and in what levels? Free, Casual and Advanced do share some problems, but I am sure they all have their unique faults.

A couple off the top of my head are:
GM being a bit of an iron fist ruler
and
GM losing interest in the story and letting it drift off.

In any case, please, chime in, discuss, see if we can't find ways to avoid these pitfalls in general!
