"I built the Velociraptor: Biplane Rescue Mission with my 9 year old daughter. She loves Lego's and Velociraptors. It didn't take long at all to put both parts of the kit together. I let her figure it out with the instruction book. The pictures in the instruction book made it very easy for her to figure out what piece she needed, and where it needed to go. Once she had them put together we were able to play with them for a while. I got to have the baby raptor and she played with the big on. She was really excited that the raptors could easily "interact" with the biplane, and even had them hanging from the chain trying to rescue each other. We had lots of fun, and I made sure we put ever piece away, including the spare pieces, so that we didn't step on or lose any. I look forward to adding more Lego kits to our already growing collection. I just wish they weren't so expensive. It makes it hard for us to buy a few from each series for us to build and play together with."
