I don't think the next golf game we see whether JNPG2 or TGC2020 takes a big leap graphic wise no matter what equipment you have. The problem is and EA Sports figured it out with TW and then Rory that there just isn't a big enough audience to pump a big chunk of change into it so what we get next if there is a next might have more bells and whistles but not a big leap graphically. The truth is the best looking game was Rory with that Frostbite engine but it didn't sell. Golf video game are a niche market and younger people don't play them. I am happy with what we got just give me a game with more bells and whistles and some 3D grass with a career mode and I would be delighted. By the way only 47 guys completed the weekly PGLS event all four rounds which proves part of what I am saying about audience.
IF it is done correctly it surely can become a great title that can make you money. Unfortunately nobody is doing it very good with marketing or game options that rival some of the great titles that kept people playing. Microtransactions are key also though to keeping a sustaining fund of money coming in BUT if you go hog wild on it with pricing you will just scare off people and not make much money. I thought PG did a good job on it's pricing but even then it could have been more like $4.99 a course or even $9.99 depending on the course.
Again it would have to be done right to bring in some good cash.
