One of my favorite games is All Flesh Must Be Eaten, which seems to be the go-to zombie role playing game for many people. I am one of those people who love the system.

Is there any All Flesh love here?

I've got the PDF's, and would love to at least play it once but my players tend to be a little less interested than I am in learning new systems.

That's too bad because it is a fun game. Right now I am running All Flesh Must Be Eaten set in the world of The Walking Dead

Fundamental problem I have with it is that it seems to be many genres instead of generic zombie. I can handle a single story game (say, Resident Evil) but the fact that they try an spread across many genres just seems to dilute it for me.

It definitely benefits from someone having a clear picture of what kind of zombie horror they want to do. I've got a campaign in the hopper that's based on some of the elements from Left 4 Dead - I think the "special infected" there provide some really good roleplaying opportunities in terms of splitting up the group, trapping people, etc.

I am using All Flesh right now to run a The Walking Down game. I have posted session 1 in my blog (see my signature) and am currently running session 2 (and posting here) and will have that posted tomorrow
