Issue #308 of the Roleplaying Tips e-zine features an article about taking baby steps when you design a new campaign. In a nutshell, you pick an idea, ask yourself some questions about it, answer them and then move on to the next idea.
It lines up nicely with Worldbuilding Questions and Start Small, too.
This is how I am approaching my Steampunk campaign. After only two games, it is already changed course wildly from what I originally envisioned, all due to the efforts and interests of my Players.
I love it!
Next game will be interesting as I will be giving them “what they’ve asked for” (either directly or through character actions). I look forward to seeing if they truly want what they requested. 😉
Nice! It’s always gratifying when that happens.
If you’re interested, this’d be a fun writeup for our Open RPG forum. 🙂
