I seriously doubt they will just completely shut down the site (PC version, that is), as that might entail some major civil issues. My belief is the site will stay up, but what it is now, is all it will ever be.
Now, like I have said multiple times, WGT knows where it stands, and they know there is no mobile version out (if there is, it is cartoon golf), so they are only and primarily focused on that aspect. The owners are known for staying "ahead of the game". However, once the "game" catches up, or passes them, they are already on to the next "game". When I say game, I'm not referring to golf, but business. Think about when the major problems/bugs we're now seeing first began. Right about the time WGT asked for "Mobile Beta testers".
They're not stupid. They know what's out there, and they know it is unrealistic to even attempt to stay #1. But, they will be #1 in mobile golf for at least a few years.
I think 90% of their focus is on mobile and 10% is on the PC version. This is one time I truly wish I was dead wrong, but I would and will bet my last dollar I am right.
It's very smart business sense. This is not, and never has been a customer oriented business. It's a money-making business venture, pure and simple. The only thing I've ever seen asked for, and received in the 2 years I've been a member, is yellow Callaway balls.
I will add, though, that the one aspect of WGT that has never failed me is, oddly, Customer Service. They have been the over-the-top quick and responsive, and have always done more than what was needed to satisfy my complaint or report.
This is a game for gamers and their egos, not golfers. Some people know what I mean, most don't and won't. When you can do a multiplication on a calculator and put the ball within feet, or even inches, on 90% of your shots (if you hit the little sweet spot line), it is not realistic. It's cool to do that and "feel" like you did something. But it's no different than figuring out a rubics cube. Once you know what to do, it becomes monotonous.
I think the majority of active players are those who enjoy playing the game with others (AS, Match, Skins). They come here to relax, enjoy some time spent with friends, joke around with each other, and the banter. That's wonderful, and it's great that they can do that (occasionally, since there is a serious issue with doing that at the moment). But, those players are also at the very, very bottom of the ladder/totem pole when it comes to getting anything they ask for. That part of the game produces, probably, less than 5% of the revenue WGT takes in.
If WGT charged 5 credits to set up a multi-player game, it might move up the ladder in regards to getting fixed. But, it would also decrease the multi-player games by 50% or more, and if those players just quit playing altogether, it would put a very tiny dent in the WGT coffers (probably not even noticeable). So, either way, it's not worth the time, effort or money to address any of those player's complaints.
Just my thoughts.
