I'll admit that Wii golf was fun when I first got it for my kids, but that fun wears off quickly unless you enjoy playing alone.
What you don't get with the Wii that you do get here is the online community and friends that you will make.
WGT's endless challenges and frustrations that can go with the game is what makes this game a continuous challenge that is more comparable to real golf. Something that you can't find in any console golf games.
This is my opinion at least.
