Also, the choice of 19x19 for Go is not arbitrary from a game design point of view, though it's difficult to say how it got there historically. There are good reasons the board should be 19x19 rather than 17x17 or 21x21. And that is that with 19x19, the corner/sides of the board balance the center just about perfectly. With anything smaller, the center is worth less than the edges, and with anything more, the center is bigger (and what happens on one side of the board also has less impact on the other side). The balance results in fun, strategically interesting games in which players have a lot of viable whole board strategies.
