I was in the gaming club in HS in 1979 to 1982, and we basically played military strategy games and D&D. The Tom Hanks movie still resonates, because I remember thinking I didn't know anybody like the characters in our club. My parents only wanted me to balance it with 'real life', getting out and breathing some fresh air (in Brooklyn ;)
