> As a player, your goal is to win the game, period. But for everyone else, including spectators and the whole support industry that is built around the game, it doesn't matter who wins. It matters only that the crowd is entertained. A player being too good makes the game boring, and so it is discouraged.

I think this misses the point that in many games, for many players, they simultaneously have the role you describe as "player" and "spectator"; while they want to win the game, they want the game to be entertaining and not boring, as well.
