) What is the optimum player count that you like to have in your own PbP games? Why?
I will never go over 6 as a personnal rule, weither in table top or play by post. I find that 6 is already stretching it too, but then, you have to make some exceptions for more people to have fun. 4 is the optimal number. Over 6 combats are VERY hard to balance, as well as being extremly long since there are a lot of participants, vs combats with 4 players where everything goes by a lot faster
2) Game Lulls-- how do you handle these as a GM?
I poke my players throught our OOC thread to find out what's going on every once in a while. Fortunately for me, I have some dedicated players that help me do that. (I'm looking at you bowen...)
3) As a GM how do you feel about pacing your PbP?
I try to let the players decide what they want to do most of the time, while giving them a general direction, and as much options as I dare. Exemple: In chapter 1 of the thorny trail, my players decided to try tracking the wolves they were hunting instead of investigating the wood witch that rumors told knew these woods well. They all failed their track checks miserably, and thus went to see the wood witch, she helped them. Later on, they needed to raid a goblin outpost. They could do a lot of things, like negociate, free the prisonners (they did that), ally themselves with a nearby dragon, and anything else they thought of.
4) Combat: Detailed or Abstract? Why?
Detailed, round by round, action by action, with maps, as much as possible. It's just where i'm comfortable, i don't like being vague.
