That's not so clear, Mochaman. Even Nivlac was posting TWO screenshots to this forum, saying they were "breath-taking".
Remember, WGT uses static photographs, whereas TWO's spectacular (at the highest setting) graphics are in constant motion. The surf is breaking on Pebble Beach's famous hole 7, birds are screeching and chirping and flying over your avatar's head, etc.
So, while WGT graphics, all things considered, may be said to be superior, TWO's graphics are by no means second-rate. They're superb as well, and so are the seven full 18-hole courses and the game-play on them.
I believe both WGT and TWO are superb golf games, both with their own advantages and disadvantages. I prefer WGT for the time being, particularly thanks to all the intriguing equipment options and variations.
