Rich Redman (who worked on the d20 Modern RPG) offers up some good advice on writing adventures in these two columns: Adventure Writing, Part 1 and Part 2.
This is an area I can never have too much help with, and I hadn’t seen these before — hopefully you haven’t seen them yet either!
Pretty good articles. Probably the most useful piece of advice is “don’t write too much”. Your players will almost always go in a different direction than you thought they would, so be prepared to improvise and take your story elements to where ever they go. They don’t necessarily have to follow the road you laid, but they can still get to the destination.
And if not, as long as everyone is having fun, who cares?
Yep, winging it is a good thing, and overprep is a bad thing. I couldn’t agree more. 😉
The article is solid advice for anyone interested in freelancing for tabletop rpgs, whether you are writing adventures or submitting other materials.
