How-to: Writing Scenarios
I wrote a scenario writing tutorial awhile back and since it has remained largely forgotten. BradyLS and Greek Geek though put in a good reminder on BGG so I thought I would pull it out, dust it off and run it up the flag pole. It is by no means a definitive document, but you may find some good things in it. If it helps make better scenarios, then bonus. Grab it from the Depot.
