Wow - and here I was posting (on another thread) about whether or not I believed 8 to be too young to understand the game. I'm finding that D&D can be an awesome kids' game, depending on how you spin it for them.
For instance, all of my children (11, 10, 8 & 7) are familiar with multiplayer gaming and MMOs as we have played Minecraft using a multiplayer server via LAN before and WoW for the older children. This has helped them immensely in terms of learning to work together to accomplish more efficiently. As a case in point - when we were all playing Minecraft before I turned them on to D&D, one of the older children was attempting to build a house...of course the youngest could not stand by and watch this and started assaulting the other child (in-game) causing the older child to die and lose their equipment. From that point I made sure that any vengeance would occur in-game rather than outside it and that it's 1:1.
As all of this is ongoing my significant other and I are playing in the same server, building houses, collecting resources, etc. By the time the children worked out their drama, they couldn't help but ask how we had managed everything that we did so quickly. The answer (obviously); working together rather than trying to tear down one another's accomplishments.
Fast-forward to D&D time...
Yesterday I ran my first D&D game for my 8 & 11 year olds, with the significant other as a third player. Using The Fey Sisters' Fate by Goodman Games as a one-shot adventure, they totally jumped to the idea of working together in order to overcome obstacles, whether or not it involved combat and actually looked for ways to resolve conflicts without violence. I find this strange because they could have just as easily used violence (I didn't openly incentivize a non-violent approach to encounters) in order to move the story forward. It was a great experience for me overall and one that humbled me a bit because I had previously believed that D&D was "an older kid's game" and there would be no way it could hold their attention for a long enough period of time to actually get through an adventure.
Of course, I was all wrong. The first question they asked as soon as I walked in from work today was, "Can we play? Right now?"
I loved it!
