I love video games. My favorite would have to be Sid Meier's classic, Civilization. In college my friends and I would play Civ III in multi-player mode in marathon sessions, some lasting more that 36 hours. It was insane. Fortunately for me, though, the tales of how these games transpired mattered more than who actually won.
Since graduation, our gaming group has spread out across three continents but we still manage game or two each year, albeit only for only a few hours nowadays. So, what has gaming taught me: Don't live to game. Game to live.
