We planned our Dragon Universe party about 2 weeks in advance and as luck would have it, Mother Nature would decide that the unseasonably warm weather in Minnesota should grind to a halt the day we planned the party. As a result we had a much smaller turnout for the party than we expected, but it also turned out the kids got twice the men and dragons they would have if the party had been full. The 5 kids present loved the development of getting twice the bounty!
I was a slacker and didn't look at the hostess gift until the night before. 200+ pieces and I realized that the hostess gift wouldn't be built for the party. I displayed it in the box, along with the door prize gift. (The next day after the party the winner of the door prize and my kids had both built the dragon air ships. It took a while but it was really fun for my kids and I!)
We colored space universes on cardboard and opened our dragons or Alliance members. The kids helped one another build the toys if they couldn't do it on their own...or they asked my husband or I to help.
They gathered around the computer to see the games on CD, grazed on veggies and dip and spent a whole lot of time imagining and playing with the men, the speeders and the flying dinosaurs. I'm not sure who they decided was bad or good, but I know they all had a good time.
My own two big kids spent at least the next three days playing Dragon Universe. For kids who have 462,468 toys, this is a long time of engagement.
