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.
But with all seriousness, I think it would be time to have another extra game added. The last game added was Massacre Chess before May 2009. That could be some tweaky variant but I also still miss the Classic Dots and Boxes game.
joshi tm: I always have a lot of game ideas. Two that I will share again, and which are variants and hopefully would not be too much programming are:
Logik-6: Logik-6 is the same game as the popular Logik game, but with 6 spaces instead of 5.
Ludo Express: Ludo Express is the same as regular Ludo, with the following changes: (1) Get out of the start with either 1 or 6, (2) Roll 2 dice each turn... double mean nothing special, (3) Each dice is separate - like Backgammon, you first make your move with one of your dice, and then the other - with the same or different piece.
Ludo is already a popular game, and quicker games are always popular - so making Ludo an ever quicker game would work very well.
Of course I have many other ORIGINAL game ideas, but these 2 are variants and I wouldn't think would be a ton of new programming.
