Henry said:The biggest mistake as a DM was my unintentional mistreatment of a friend who drove 2 hours to a game only to have him sit doing nothing for 3 hours because I couldn't find a convenient place to drop his character into the story. He left disappointed and upset with me, and I don't blame him. It was then I learned a hard lesson: Story be damned, there's people playing this game, too. It was a mistake I've tried very hard to never repeat since.

Piratecat said:I do that all the time, too. I've started circling SR and DR in big red pen and labeling it "don't forget this, moron!" It's helping.

Running Heart of Nightfang Spire for too long, and choosing to run Bastion of Broken Souls.
Seriously.
