Difficulty Level (Player Properties)
Determines the difficulty level that the selected player plays on. Difficulty level settings can be adjusted on the Difficulty Levels page.
NOTE: if the player is a human player, and the level is set to "Any", the player may select any difficulty level he or she wishes. Otherwise, the human player has no choice and must play on the difficulty level specified on this page. If the player is a computer player, setting the level to "Any" forces the AI player to play at the Default Difficulty Level as specified on the General Settings page.
