Dropping pieces makes shogi a very dynamic two-player game, and its play is much more satisfying, I think, than loop chess because of the balance of weakness and strength with piece movements.

If there are ever multiple-player games on BrainKing, there is a very entertaining 4-player version of shogi, yonin shogi. Effectively, you can play the game where two players act as team partners. Maybe that could be implemented even now on BrainKing without having to accomodate other multiple-player games?
