Introducing three of my kids to D&D. One of them asked a few days ago how old he had to be to play, and I said 0. It snowballed from there and I have now planned an introductory campaign for them after brushing the dust of my D&D 3.5 rule books. I'm going to the library in a little bit to print out character sheets.

They're aged 10, 11, and 13, and I'm pretty sure they'd all get bored if the first session is all spent picking a character and learning the rules of character creations, so I'm flipping it a bit on the head: They'll jump straight in with class and race unspecified, and introduce things as we go.

The "tutorial" starts with them being tasked with clearing out a kobold lair, after which they will find some gear that will be tailored for each class. Depending on what gear and weapon they choose, I'll help them pick a race and class.

Then comes more puzzle-oriented task, which will introduce them to the skill system.

Then they'll Hopefully become lvl 1, which is when I'll introduce them to features and spells if applicable.
