We had a blast at Old School Teen Time [2]. We had over thirty-five participants. The parents dominated while the teens couldn't get over the fact that there were no on/off switches. Staff got involved too and by the looks of things took the games seriously. Gamers got a kick out of that as much as they did playing.
