generalepsilon writes "Researchers from the University of Washington have found a key reason why Starcraft is a popular spectator sport, especially in Korea. In a paper published last week, they theorize that Starcraft incorporates 'information asymmetry', where the players and spectators each have different pieces of information, which transforms into entertainment. Sometimes spectators know something the players don't: they watch in suspense as players walk their armies into traps or a dropship sneaks behind the mineral line. Other times, players know something the spectators yearn to find out, such as 'cheese' (spectacular build orders that attempt to outplay an opponent early in the game). Rather than giving as much information as possible to spectators, it may be more crucial for game designers to decide which information to give to spectators, and when to reveal this information."
