Here is my suggestion from June 2003 (Sorry Nof - I claim naming rights!):

http://brainking.com/en/Board?bc=26&ngi=16070

which was:

1. Dark Backgammon Race (or Regular/Nack/Crowded?)
- Basicly just like regular backgammon. You don't see ANY place that you don't have your own piece, so you will never be "blocked" and allowed to move to any place.

Now when you move to a place that is open, your piece stays there. If you move to a place that only has 1 opponent piece, you take it like normal gammon. If you move to a place that has 2 or more oppenent pieces, your piece will be placed back to the bar like it was taken out.

So this game would involve a lot more strategy - making you want to set up many places of 2 or more pieces to take away your opponents pieces when they land on you.

I believe this would be better as Dark Battleboats Race. Also I'm debating if it would be good to hide the opponents dice or not.
