The gameplay of Tiger Woods 2005 is very similar to 2004, although there are several new courses. Tiger vision is neat in single player mode, but annoying in online play. The improvement I really like is ball placement. You can adjust your stance to keep the ball low for extra distance or shoot the ball high so it drops right on the green.
There seem to be some kinks to work out online. You can spend a lot of time creating a character only to lose the look you created due to a glitch. The only remedy seems to be starting over from scratch... attributes and all.
