Mind you – you can never guarantee that any given gaming crew will have a good time playing your adventure. A million things can go wrong, up to and including incompatible styles between yourself and the group playing through your dungeon. Games go off the rails all the time, and there is nothing you can do to prevent that from happening. What you can, and should, control is the quality of your design. The better adventure you write, the more likely it is to facilitate a fun night of gaming for a group when the GM picks up your adventure.
