I learned about Attacktix from Mark Johnson and picked up a starter set and booster at Target last week.  I thought the kids might get a kick out of them.  They’ve played every day for the past three days, including a three-way battle with the Rude kids.  It takes about 30 seconds to learn the rules, and don’t expect any deep strategy.  It brings concrete rules to something all us geeks did as kids still do – have pretend fights with our Star Wars action figures.  The most innovative mechanic is movement, which is done by counting clicks on a roller-wheel under the base.
