My son turned 11 this past week.  On Sunday, we invited another family that has two boys around his age to join us for some Laser Tag, then pizza and cake back at our house.  I've played maybe 6 sessions before, but I rocked it out, crushing all the grandpas, new moms, and over stimulated teens.  It's pretty difficult to come out on top out of 36 and 34 players back to back, though, because it's such a frenetic, haphazard setting.  There are supposed to be 3 distinct teams, but many people wander aimlessly with no team concept.  It's not something I do regularly, but it was good family fun for all ages.
