There's no question at all: Lego Universe is a game built for children. Creative Director Ryan Seabury says the primary audience of the game is ages 8-12, and the interface is very clearly young user-friendly, with big, brightly colored buttons, and easy-to-use UI widgets. The game centers on collecting "imagination," and while there is combat in the game, it's simple and trouble-free, more fun than strategic.

But here's the thing: good game design is ageless. And Lego Universe seems like a tidy summation of everything both developer NetDevil has learned about making MMOs, and Lego has learned over 75 years of making classic toys.
