True, chess is "just about completely solved"
but shogi's unique side-switching captured-piece drop rule ( mercenary paratroopers for the win) that was added in the 16th C. (?) makes it a far more computationally difficult problem. I'm still in the "learning good openings" stage but find the game fascinating and refreshing - the old regular chess games may move to the back of the closet.
Chinese chess is also interesting but one chess-sister at a time...
