I am a participant in the Tenkar’s Landing Crowdsourced Sandbox Setting. It is an interesting concept and it is cool to see all the ideas and how people consult their neighbors to sync up features like rivers and roads and adjust maps to flow with the ideas of others.
I picked a swamp hex. In my campaign I don’t have players running around near a swamp, so my ideas are limited in application to my game. However, other’s hexes have ideas and terrain more in line with where my players are running around, so I can glean ideas.
I see this growing and becoming a very thick book, even a series of modules.
I can’t wait to see how it all plays out and fits together.
