100 Adventure Ideas (DnD Other)

Remember as you add ideas that you are writing a story. Things that make both quests and novels interesting are falsities, Imagery, and most importantly options. Players can't just play along to what you say they should do. If they don't want to go explore the castle they don't have to. Make them decide what encounters they do. Allow them to choose to whip off their disguises and battle the unguarded baron or to leave with the information they have gathered. As a DM you have to be vigilant of what the party might do. Problem solving makes for a good quest. Also, make sure that you do not have too many crazy people in your campaign. Also, don't be mean, some people put a lot of effort into their characters. Ask the players what they want to do.
