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'm playing a chinese gentleman in a game of Xiangqi, and I know he would prefer using traditional pieces. Unfortunately the current implementation of xiangqi here only has westernized pieces. Perhaps the pieces on wikipedia (GPL-like reuse license) could be added to the system for use on Xiangqi? A good start would be http://en.wikipedia.org/wiki/Xiangqi#Pieces, where can be found some attractive piece images.
