I would like to see the following:
1. Lefty player option. Seems like a no brainer to me. TW has offered it for years.
2. More spin naturally on the more lofted clubs; even after changing the impact point, most approaches roll out much further than a typical shot with a wedge or short iron.
3. A slight increase in distance to make reaching the fairways a litte more realistic. I am just an average golfer (16-18 hcp), but my average measured distances at golfsmith were considerably longer than the hack that I am in this game. I wouldn't mind the misses be accentuated more by hook, slice then just straight offline. I would be willing to give up directional accuracy for more distance which would make the game more realistic for me.
4. Maybe a few club options for the standard set. I would bet that your average golfer might have 1 less wedge and either another hybrid or wood. If the starter profile is based on your average golfer, maybe replace the 3I with another hybrid.
Other than that, its a fun game, good graphics. Plays pretty close to an actual round aside from the above mentioned suggestions.
