To begin with I do not play 3-click much. I've tried it but not to the extent that I can give any kind of real opinion as to it's virtues and failings.
I'm reading through this thread and it's full of the usual suspects. That is not meant as a derogatory statement it's simply an observation. I'm not even sure what the structure and compliment of the closed BETA team is or was. It sounds like from my limited knowledge that I have that the closed BETA group is becoming in the eyes of those outside or is being associated with an elite group that seems to direct the game into channels that they prefer. I'm sure PP keeps some of this in check. I'm also unsure of how collaborative the process is.
What I would like to see here are the opinions of many more 3-click players. If the general consensus agree with the OP then the discussion should be open for some changes. But where is that on the road map or is it there at all. This should be clear to the closed BETA team in my opinion.
Does PP inform the group what their current priorities for game development are? Are they very clear about their road map and keep it updated? At any rate it sounds like the game and it's player base are ready for a change and for a couple of reasons if my limited impressions are correct.
In the beginning it was OK for PP to rely on a limited group for BETA testing and for advice on how to move forward. If the goal is to now expand the games commercial appeal in advance of console release or even just to keep developing the game and expands it's PC player base then closed BETA should be a thing of the past and PP should start developing access to OPEN BETA TESTING and provide a board for feedback from the entire player base that wishes to contribute.
This could be done two ways. PP could just end the closed BETA group and rely on the forums to gather feedback on each new release but that would be unwise as it would create a very small Q & A team. The other would be to open up the BETA so all of the player base can test the next build and provide some feedback. I've seen some games take this route and it is almost always beneficial as no one who wants to contribute feels left out. It allows more of the player base to feel involved. Most importantly the developers get more accurate feedback from a larger base which is almost always a good thing.
I cannot imagine why 3-click dissatisfaction is falling on deaf ears in the closed BETA group. Unless there are just too few 3-clickers in the group. Perhaps PP will revisit the issue but their current development plan has it on the back burner.
As to difficulty levels, there are plenty. Tour Pro should be the Elite playing group and should make up a small percentage of the player base. Pro on the other hand should be difficult but accessible to a significant portion of the player base. TP should be OFF/OFF and if PP adds the Grid and BLI off within the API, then even better.
Physics and swing mechanics. PP is so very close at least from my limited RTSH experiences at PRO level. I think across the board if you return TOUR PRO to OFF/OFF then PP could reduce the overall tempo penalty slightly making .24 - .26 non penal which opens up the tempo for a bit more variance without any penalty. I personally do not need to see this but I think overall the game is getting too close to being too frustrating for most players at anything above Amateur. I think it's a change that would be good for the games overall appeal.
That is my personal position anyway even if it takes a little bit away from my personal enjoyment and challenge. I would agree that some of the short game club mechanics require some minor tweaking but over all at PRO level RTSH the game seems a bit too difficulty at least in establishing decent and go to tempo for every shot because the tempo is too restrictive. I'm pretty sure the supposed 10% or the gaming savants will disagree but maybe not. I think some of them would like a little flexibility in tempo mechanics.
For myself the game is great but I'm a bit of a masochist when it come to golf video games. What is required now is a better general consensus on the state and direction of the game. Perhaps a mass e-mail survey from PP would be helpful to capture some of the silent majority and open up the BETA testing to all. Make it easy to access and test the BETA build and market the change sufficiently so everyone that visits the forums or the main website are aware of open BETA testing and how to contribute.
