If you want to play an online game with your kids and enjoy it, this would be it. There are plenty of other MMO's, and browser-based MMO's, but you run into so many social issues that you don't even want to try for very long. Most of these same MMO's are also not themed for kids very well. Here, they have known characters with plenty of missions and storyline to play through. The developers really took their time looking at what kids will enjoy. They enjoyed collecting all of the Nanos and didn't really care too much that they were to be weapons. They continued to play with their favorites, even if it wasn't the best match. But, hey it is their game and they are having fun.
