Would it be possible to add 4-player chaturanga to the offerings on Brain King? I enjoy this game very much and think that others would, too. I personally prefer the no-dice variant and alliances between red and yellow, and black and green, as described in Gollon's modern version of the variant.
Dare I say that Yonin Shogi (4-player shogi) is even better?
