When do you ussually play? Would you be interested in mini games that run for a day (6 to 8 hours). Something along the lines of starting a new seed at 0900 (9am east coast time USA) and playing the map with the single mission of killing the dragon. Then the seed and game would be over. With 6 people working it can easily be done in 6 hours or less.
Stay fluffy~
God forbid; good sir; that I should assume anyone only play for four hours a day.
