I have had a blast with these, thanks for some fantastic ideas.
They would need expanding for publication. At the moment they are presented with your undead scenario. You could rewrite as generic rules and include the undead scenario as a separate intro example. Perhaps it would be an idea to offer several scenarios for different levels, say a couple of basic level, an intermediate and an elite level scenario. Or else offer a linked campaign (which might be more work).
I'll tidy up my notes and send you the games I produced for last weekend if you like, so you can see how I approached it for a more experienced party.
