The more innately complex a game is, the more room for emergent gameplay.
EVE Online is a very complex game. The game takes place in outer space, where upwards of 50,000 people concurrently play, buying and selling and stealing and killing. Players form corporations that can seize control over entire solar systems and star clusters. Corporations form alliances and start star wars against other alliances.
In this bizarre example of emergent gameplay, the player, The Mittani, plays the game by not playing the game.
The Mittani rarely logs into the game, preferring instead to act as a prime mover--an outside force, more concerned with the big picture than the day-to-day skirmishes and operations of the Swarm. Communication becomes a game in itself. "I'd get 20+ [reports] a day and, at one point, had 35 separate Trillian windows open," he explains. "AIM for Americans mostly, MSN for the Euros, and ICQ for the Russians."
And to top it off, The Mittani is actually winning the game by not playing it.
