Basic D&D. It's amazing how much the game has come. It's also amazing that I am no longer stealing graph paper from math class to make dungeons that make no sense at all.
How exactly did those orcs eat? Why didn't they get eaten by the dragon? How did the dragon fit down the trapped staircase from the middle of the woods? Did every dungeon have to have a secret door in the boss monster's room that led to the treasure and the way out? Why didn't my players ever think to not go down the trapped staircase and instead find the way out from the boss monster's lair? It wasn't probably fitting through the secret door to go after them so they could waltz down and just take the treasure.
