When a game is played in turn-based mode, the game time does not matter - the number of turns matters. Maybe you can easily get the average number of turns in a game by examining completed games, and then display that alongside the average number of minutes.
I'm still trying to find a good turn-based game to play with turns that are long but fewer in number.
