Just a note for posterity, and clarification:

The original Demo quest was created by Phantom Menace and Nightmare James for ZC 1.8x->1.9x (!!), and updated over the years by Nightmare with some participation from ZC developers, ultimately culminating in Demo SP (for ZC 2.53.0), released this year.

This is a wholly different quest, meant to demonstrate 2.54+ ZQuest editor features, and modern design techniques using ZQuest editor features that did not exist prior to 2.5x.x.

I'm not sure how much I will be involved with the overall quest structure, or what direction it will take. My present position is undefined, and may continue in a support capacity, as with Demo SP, although I may take a more active role with this, as time permits.
