Playing online for the PS3 was nuts. Some fool in a lizard suit was outdriving me by 60+ yards all day. He was regularly getting 2s on the par 4s.
It gets nuts when you play the 4 player stroke play, and you can see the shot paths of all the guys while you are hitting. Lay off of the acid while you're doing that!
About the only online games that I dominate in are baseball and football.
