I've thought of a new backgammon variant (or at least one that I haven't heard about before). Crowded Antibackgammon. The initial board setup is like Crowded Backgammon, as are the rules of movement. Winning conditions are as in Antibackgammon: force your opponent to bear off first. I know at least one other person who's quite excited about the possibility, and it's probably simple to implement.

Does the concept interest other people too?
