There are a lot of computer golf fans around, but they are all split up among all the mediocre golf games that currently exist, everyone has their own favourite among them but the one thing I think everyone can agree over is that they all have a lot of flaws in their own way. Someone mentioned TGC2, well I think 57% positive reviews on Steam speaks for itself? Links itself still has a surviving dedicated community of people who considers 16+ years old games still being the best golf game out there, which is pretty ridiculous, and I say that while counting myself among them. LinksCorner unfortunately had to remake its forum recently and a bunch of people haven't found their way to the new forums yet, but its still very much an active community, along with the LSPN website. A modern quality golf sim with a big name behind it could certainly get people flocking together again.
