Urban Theme, with apartments / city skyline, with updated parkland type trees.
This would be really interesting I think.
I was about to say to focus on color palette changes for the original themes, making all place-able objects universally available across all themes and focusing on adding additional object such as different buildings, houses, structures, trees and bushes added to the universal object list. I would rather see HB Studios focus on these before adding another theme. I think before adding another theme the developers should be able to cross a couple of other items of their lists.
1. Getting a very close to finalized swing mechanic that has as much parity as possible between the different standard input devices without any enhancements. A swing that HB Studios is happy with as they want the game to be played. This would include the adjustments to the short game and any adjustments to the "shot adjustment" model. HB will soon want to have these mechanisms pretty much locked down.
2. The addition of uphill and downhill lie mechanics with an optional local "at your feet" grid that can be toggled on or off in the settings menus. Any other surface, object collision and ball physics. This would include any adjustments made to wind physics on the ball, especially when high winds and proper spin exaggerate the winds effect on the ball.
3. The addition of different modes of play. Match Play, Best Ball as examples.
Once HB Studios can cross some of these off their lists in some way, I would then focus on object additions and reworking old themes before investing too many resources on any new themes. That being said if HB Studios prefers to focus on new themes an Urban Theme would be my vote as well.
