Battlebots is cool, but battlebots are expensive. Plus, if you're not very good at the end of the day the whole point is to wreck them, which makes it more expensive still. So, some enterprising individuals came up with battlebricks. Same concept, but this time with legos. They're not real fast, they don't seem to be all that violent, but they are cheap and they come apart real good. What's not to love?
