TW 2011 is just a bad game. It has 'features' that allow teams to cheat, the online experience is HORRIBLE compared to previous years, and they have made the Pro Shop kind of a mini-adventure-game where you stumble around, trying to figure out what cryptic pattern of stuff you need to buy to max out your golfer, all while spending more and more and more money via MS Points.
TW 2011 is a horrible version released as nothing more than a money grab by EA.
The last good version, server issues or not, was 2008.
