8-ball, 9ft table, 4.125" pockets... but not pu'er 8-ball 普尔黑八 like is normally played here (10-ball would also be acceptable. Same table).
I enjoy 8-ball the most, as I am most competent at it and being here I play it more often (as it is the game most people play, and an easy way to guarantee a playing partner). I personally prefer 10-ball, especially the safety side of the game.
If it's a desert island scenario, I'd choose 8-ball, as I consider myself pretty tasty at it and often play left vs right hand anyway. But, if only one game existed, I'd choose 10-ball. It's a well-balanced game with no slop, that allows defensive and offensive play.
