I build lego ships for my boys and my brother. Everything I build is playable (micro for playability in little tiny hands), as accurate/detailed as I can get it, sturdy and explodable (seems counter-intuitive, but explodable means it can be "blown up" in a controlled way, with built-in break points that allow you to easily reconstruct in anticipation of tomorrow night's space battle. I love sci-fi and space, I was raised on Star Trek and Star Wars, I read space sagas like they are going out of style.
