Recently my son convinced (or tricked) my wife into buying him a Nintendo DS. Just so I wouldn't be forced to fight endless Poekemon battles I brought a game cartridge that had a number of board and card games on it. Of course my main interest was the chess program it had, but I also discovered it had a Shogi program as well.
For those that don't know Shogi is Japanese Chess, although historically it may pre-date Chess (at least in its current form). While the games have plenty of similarities, it is the differences that make Shogi interesting. Probably the biggest difference is that capturing a piece in Shogi means exactly that. Any piece captured joins your army, and can be dropped onto the board (in place of a move) in the same way as Bughouse. The often creates wild swings in the game where one player sacrifices material for a mating attack, and finding it unsuccessful, gets buried under an avalanche of pieces coming the other way.
Probably the hardest adjustment for me when playing was the lack of long-range pieces. You start with a single rook and bishop and losing those (as I often did) was catastrophic. Also it does take time to get used to the symbols on the pieces, as they are in Japanese.
There is a chess/shogi crossover as the strongest player in Shogi history is considered to be Yoshiharu Habu, the only player to win the 7 Crowns (the 7 leading Shogi tournaments) in the same year. He is also one of Japan's leading chess players with a rating of 2400. This is what he did to English GM Peter Wells in the Essent Open 2005
