Fallen Seraph
First Post
I usually plan out some broad strokes of an adventure, with some more detailed specific points that are likely to come across and let the players go about playing through the adventure as they see fit.
I normally take a sort of backward approach to creating an adventure. I usually start with the ending and final conflict and then write backward to the beginning.
I don't have a single set method I use all the time, and instead use different methods for different games/campaigns.
