LOL....you can determine that a completely new swing mechanic isn't compelling after one hole? Um, ok.
Fact is the demo was completed in mid-January to make it in to Sony and MS in time for release. The majority of code tuning and polishing took place over the final 6 weeks of development. The Devs have stated that many of the issues being reported in the demo have been resolved in the final code, all of which you are critical of. Also, many users felt the same way about the swing mechanic change and putting interface. However, many of those same users have put some time into the demo and are reporting back that they see why the changes were made and they feel the changes were time well spent and instead of skipping the game, they are now either considering buying it or have pre-ordered it. TW13 is not going to appeal to everyone and it seems your mind is made up after one hole. I hope you find what you are looking for some day....
