I try to stick to one idea a week, but if I had this one this morning it would have my first post.
To the players:
If you could put something you like in a dungeon what would it be? Is there a specific mechanic you like from another group dungeon you do?
Do you want a specific type of enemy? Like zombies? But more, a lot, maybe fast, maybe harder to kill? Maybe you can't kill them for good, and they get back up after a period of time and begin the chase again lol idk
Would you want it to take place underwater or on the clouds?
To ESO:
Would you ever consider making a dungeon based on the player's design?
