RYO!
This board can be used as GUI for any rules that all players wish to abide by. Players are bound to follow the rules, and change the "map" accordingly. So, for instance, you could create a game where you Roll Your Own dice.
All Attacks WIN (D1 v D0).
Each player has an ON board/OFF map "Territory" which they use to allocate/move units by way of fortification onto and off the board as the outcomes of play dictate.
Once a player has been eliminated, any subsequent player can attack his "home territory" so that he no longer needs to take turns.
