A quality Go game consists of a single thick piece of wood wit the grid engraved and painted on one face. Sometimes the large block of wood is made with small feet. The block measures about 18 inches x 18 inches x 8 inches. The pieces are small stones, black and white sets, polished. The grid is 19 x 19 and has eight heavy dots in the four corners at position 4,4 and along these same lines midway between the corners.
Having said all that, I recommend you pick up a cheap cardboard set and see if you can understand the rules and find someone that wants to play. Otherwise, you will have a very expensive coffee table extension.
I had to give up Go when I was learning chess because there wasn’t enough room in my head for both games.
