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.
Rainbow Road: It has always been my understanding that a game doesn't have a copyright. Certainly, a name can be trademarked, and a description of the rules has a copyright. But you're free to make a game with the same mechanics. Just don't copy the rules verbatim and use a different name.
