Re: Peasent Campaign
I never ran one, but have been toying with the idea. However, friends of mine played in a very long running game where they started out as peasants and ended as beings of God-like power.
The GM started them out at 0 points with 50 in Disadvantages. I've always thought that was a little tight, and would suggest either 25+25 or 10+40.
The best part of a peasant game as I can see it is that the PCs really do start out as humble characters who grow into their power at a reasonable pace. They start out protecting sheep from wolves, or the like, and the end of the first major story arc might be them leading their village against the harassing orc tribe.
I'd agree with Curufea that having each of them have a definite occupation in the beginning can be helpful. Helps character creation, and get into roleplaying their character more (ie if you're the lazy and commonly drunk town guard, you know to perhaps get Dependency as a disadvantage, know a little about law, and have some weapon ability).
