The Kids Are Alright

With my wife down from her surgery I have been left to do all the things she does, take care of her and still find the time to squeeze in "my" stuff.
One thing though (of many) that has taken a hit is my game time.

I have no idea really if I'll get back to my Pathfinder game; things are just too crazy on the weekends and my regular game with my kids has been hurting.

My son though REALLY wanted to play.  I couldn't so he sat down on his own and wrote an adventure involving finding a lost King and defeating the monster that took him.  It was simple really but he hit it with enthusiasm.  Remember, all those things we in the older guard consider cliche or even passe are still new to someone.
He then proceeded to grab my books, roll up some characters (it was a 1st level adventure) and play with his brother and a friend.  They were in my kitchen while I worked so I got to hear it all and answer

They spent some time looking for equipment, managing their funds and complaining about the high cost of cross-bow arrows in this land.  They heard rumors, interacted with townsfolk and then went on their quest.

They were attacked by goblins, but found clues that lead them to a treasure trove, the King and a green dragon holding him hostage.  The dragon was a youngling and not very skilled.  The fighter and the thief nearly bought it a couple of times, but they had some help from their retainers.
The king was returned safe, the gold from the treasure returned to the merchants' families and the King gave them all a reward for bravery and honor.

Not bad for a few hours of play.  And certainly not bad for their age range (8 to 11).

So when people are worried about whether kids have the interest in D&D anymore, I have to think of "The Forrest Quest".

Now good readers.  Can you also ID what version of the D&D game they were all playing?
