Well if you own the 2003 version, you cannot update it to the 2004 version. They are pretty different games. My friend has the 2003 version and the graphics engine is a lil wacky in it. The 2004 version features better commentary, more courses and fluid motion in the graphics. Think of them as totally seperate games. Both do have patches though and allow you to play online too. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
