Do you miss something on BrainKing.com and would you like to see it here? Post your request into this board! If there is a more specific board for the request, (i.e. game rule changes etc) then it should be posted and discussed on that specific board.
But with all seriousness, I think it would be time to have another extra game added. The last game added was Massacre Chess before May 2009. That could be some tweaky variant but I also still miss the Classic Dots and Boxes game.
