Halloween, your favorite things?

Do you have a favorite Halloween tradition as it pertains to gaming?
This ‘harvest festival’ is not celebrated back in Oz. Oh for sure confectioners jammed lollies into our faces, but the ‘event of Halloween was never one celebrated in neighbourhoods. Imagine approaching your neighbour and asking for candy…..never gunna happen.

These days with the kids over the 2 hour exercise to obtain free candy and look like a fool, we attend adult parties.
Another excuse for Puritan America to get her drink on and not feel guilty.

But I digress. The point of the post is this. Do you have a favorite homemade or designer made Halloween themed wargame scenario?

What tactical systems or other scale out there in the Wargame, SciFi, Fantasy world have published or shared Halloween scenarios?
