I figured TIGSource would probably be interested in this.
This is probably the funnest tabletop game I've ever played. Granted, it's the only tabletop game I've ever played, but whatever. The basic gist is more or less the same as your average wargame, except that everything you play with and on is made from your own toys- preferably Legos. The rulebook is incredibly long and needlessly complex, but all you need to read are the rules for basic games at the very beginning. There are a couple rules for how your miniatures can move and attack (measured by inches instead of spaces since you don't necessarily play it on a grid), but after that it's all up to the players.
It's not something that is meant to be taken too seriously; after all, it's basically a slightly more organized version of all those times you and your best friend fought with your action figures. But that's the beauty of it.
In any case, if you've still got some toys or board game pieces, check it out. Your inner child will thank you.
