Why not go with the alternate time control. Say 7 days + 2 days per move bonus time with a 15 day cap? That lets players 'bank' some time if they know they might be away from their computer in the future without necessarily doubling the length of the game.
(sakla) In the mood for a quick game that is guaranteed to finish within 2 hours? Create a new game of your preference, select the Time for game and set Time to 0 days / 1 hour, Bonus to 0 days / 0 hours and Limit to 0 days / 1 hours. (TeamBundy) (Bütün ipuçlarını göster)
