I understand your self criticism, before I started my first game as Mc (it was also the first time for me and my group -people deeply grounded in D&D- playing AW) I was scared to mess it all up, but as we begin the first session everything went fine.

I just go with the flow, looking for interesting things that happens, asking tons of questions, keeping an eye at fronts and how they react to the things that the Pc's do.

I had a bloody-devil gunlgugger, for him sadistic violence and demonstrations of brute force was his daily bread. He was killed by the other Pc' at the end.

I had a maestro'd who had some problem with the infected followers of the brainer/hocus, in one of our first session he killed a couple of them. Monk, one of the followers, asked the brainer (the leader of the cult) to do something about it, it was something like "I know you know that guy, but I want justice. I'm not asking you to kill him, I just need one of his hand for compensation, you know".
The brainer had a talk with Monk, succeding to persuade him not to harm the maestro'd, at least not now. And all that revenge thing just faded away.
Later in the game the Brainer was killed, and Monk became the leader of the cult.
They were all infected by a plague spreading all over the city, the maestro'd was infected too. They both -monk and the maestro'd- worked to find a cure separately. Monk succeeded finding a cure for the plague (threat clock= find the cure).
Session 12#, the maestro'd is dying because of the plague, his right hand is a mass of deformed meat. Then he meets Monk, who offers him the cure, but with a small price to pay: his left hand.
(I summerized it all just to make a quick examples, how it all happened was much more xciting)
What I want to say is show genuine interest at what happens in thw world you are collaboratively creating, and everything will find its course. Stay involved in what happens. And if your players are having fun, it means you are doing well your part.
Have fun!

hi,
with my gaming group we'd like to play something with zombies and pc's as survivors, but I feel that we need to change a few things of the basic Aw.

I'd like to know your experience about that.
For now I decided to remove the playbook, and focus on the Pc's -normal people in a special situation- how they relate to other survivors, scarcity and how the world change them.
and then come the zombies.
that's the main problem, I don't know how to handle a "fight" with the undead.

Some ideas come up, but none of them really satisfying, since all I want to do is to play that kind of setting I'd aprreciate some adivice.
Sorry for my broken english ;)
