The online play works really well. I couldn't feel any lag playing PappyKnuckles. It felt just like offline.

Aside from standard stripes/solids and 9-ball, there's also a "points" mode where you try to rack up the highest total ball numbers, and one other weird mode called "killer" that I've never heard of.

Also, as I found out the hard way, there is an achievement for hitting the cue ball off the table.

Edit: "Killer" mode is actually a lot of fun. You take turns shooting with the other player. You both start with 4 "lives," and you lose a life if your turn ends without scoring a ball. If you score more than one ball in a turn, you get an extra life. First player to run out of lives loses. Or if you run out of balls first, the player with the most lives wins. Fun mode!
