There were some pretty strange ideas expressed at the start of this post. how the heck do you play D&D without dungeon crawling?
No dungeons is normal for me.
I have temples, ships, warehouses, towers, forests, swamps, hills, bridges, roads, towns, cities, magical planes, cloud kingdoms, and many more locations.
My players rarely go looking in a hole in the ground for something to do.
My latest adventure is the first time in a long while that I have had anything like a 'dungeon'. The top floor is an ordinary two story home in the town that the players have followed 'bad people' carting 30 chickens and 6 monkeys to deliver (and they've heard this is delivered every two days).
They cleared the two floors of the home (a watch force of guards) and found a secret way down to a set of stairs. The stairs leads to a hidden temple. The end of the temple sanctuary leads to a forest environment.
The temple is basically a bridge point for the players and a chance to determine whether they want to stay in the city or move out to the wilderness. The portal is being held open by a person who has had their heart pulled from their chest and is slowly dying (evil temple people).
The opening is a limited opportunity forcing moral choice of how to handle the person in mid sacrifice and physical dilemma as they don't know where they'll end up and didn't start the day with provisions and supplies to be out in the middle of a forest adventure.
Regularly I have ambushes in town streets with all the complications of innocents. I've had merchant meetings broken up by a third party breaking in and had rituals performed in a warehouse within the town.
I blame my Shadowrun days for getting me out of the dungeon and using common locations for battle zones.
