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.
ngsinan: AbigailII is right here. Bridge is a super game, but you have to take lots of notes to play, which is not good for gaming experience.
4 Player games are great to implement here at BK, Something like Ataxx 4, Halma 4, Dice Poker 4(or even more!) or Ludo 4 where board position matters only, is good to implement at a Turn Based Game Website.
