Hmmm..... They still haven't improved on 2005. Sad but true.
The graphics are ok, but the voice overs, come on can't we get new announcers with new dialog, my gosh, it's identical to 2005 still.... boring.
Another thing I find very frustrating about the game is the hacker tournament. You have to win it or start all over again. I got in a bad spot on one hole and ended up 4 over on one hole, the rest I parred or birdied and I still came in second to a character that I had played before in the road to the tournament and beat very easily. How did he get so much better in a month?
Finally there are features in the PS2/3 versions that are a lot of fun that they've never bothered to port to the PC version. Like when you get a really good hit there is an instant replay of the swing (I'm not talking about the whole shot after the ball's come to a rest)
In summary if you don't own any version then go ahead with 2008 it's ok, if you have a previous version don't waste your money "upgrading".
