My high school global history teacher always played Diplomacy with the upperclassmen, mostly seniors and juniors with a few sophomores. The bulletin board outside his classroom usually had three or four games going at once, with no fewer than a dozen students examining them, talking about games, and strategizing. My first game was as a junior in high school, probably 2003. I was Austria. I still remember my opening - Tri-Alb, Bud-Ser, Vie-Tri. I got destroyed. The teacher enjoyed beating younger competition, so he always made sure he won by manipulating dumb high school students. I only won once in high school, I played Germany and stabbed one of my good friends, who promptly quit, giving me the solo.
