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.
I would request a "Game Request" Discussion Board page. Sometimes I just read very good ideas for new BK games on other discussion board, but they get buried in there and will be forgotten.
