I've finished the first chapter of an adventure that I will be running with my current group. If it goes well, I might release all three chapters for other people to enjoy as well.
The first chapter focuses mostly on interacting with the environment.
The second will focus on interacting with NPCs.
And the third on combat, both in space and on the ground.
Now, each chapter has points that hit on each of these three things, but the primary focus, the main plot driving point) are each of those three respectively.
This adventure is being designed to help introduce new players to the game in an adventure that helps define who they are, how they interact with each other, and where they want to go in the future.
When playing a fan made adventure, what sorts of things get you excited? What turns you off? And what crucial elements have to be there in order for it to be worth continuing?
