So I’m running the sunless citadel adventure as my kids’ first dnd adventure. My 8 year old is mostly only entertained when he crits with his great sword which is typically massive overkill, but my 9 year old is super into it and made a new friend at school by somehow LARPing the module during recess. Anywho there’s a couple tunnels in the module that just say they go to the underdark and go on for miles underground. Last night near the end of the session the party decided this was the way to go. It’s been fun seeing how differently they do the mod than my friends and I did. Our DM was able get us back on track by having me run into some drow and then a drider when it was me going off the beaten path.
I suspect my kids are less easily dissuaded, so, new adventure I guess. I had a whole folder of one page dungeons with map PDFs and I went through that for a scaffold to build from. Always kinda fun to have one of those moments where you gather up the adventure notes stack them and put em away so you can take the new direction.
[edit: okay maybe not always fun to change gears. The party entered the new dungeon/cave that I spent a couple hours turning into a proper adventure, but right after I busted out my new map they "noped" out and exited in order to instead go deeper into the underdark.
Luckily I had plan C already in waiting in the wings though this 1 page dungeon appears to be 1st or 2nd edition DnD (since AC is inverted and it lists XP amount from treasure), so I'll be spot-fixing things as they appear.
