A variety of GM playstyle questions.
1) What is the most common type of environment or terrain encountered thus far in your current or most recent campaign?
Not really been a consistent theme, but they keep returning to the Complex which has a bit of a classic weird dungeon vibe to it.
2) What is the most exotic or unusual environment or terrain encountered thus far in your current or most recent campaign?
Well, the Complex, it is a place of interlocking tunnels so large that none of the characters has explored more than half of it and it is being expanded by the army of insects that live inside it. Everything serves the mysterious Pattern which has not been explained beyond its goal to bring order.
