krybulon: You could even go farther, by having two dice everytime and allowing both to be applied to one piece, or one die to one piece and the other die to another piece. You could call it "Pro Ludo"... it expands on the current ludo, so why not?
What about a 4 player ludo!? hmmm? Sounds interesting! I personally wouldn't want to play, but some people would love it!
