The problem with sliders in my experience is when it comes to online play. What happens when you play online? Do the sliders go back to default or does the host set of sliders get forced onto the person joining or do you allow both to use their own? If you allow both to use your own then the playing field isn't level.
This is why I prefer preset difficulty levels.
Preset difficulty levels are what TGC2 basically has now. It is not enough for some, too much for others.
My understanding is that 80+% of users of Golf games do not play MP online. That means they play a course they like, or Career Mode or maybe play one or two Societies they like that play like they do. I think that is the majority of the market. I may be wrong.
While Golf games may be a "social experience", online play numbers are awfully low even during Tiger's hey day.
When I say sliders, here is what I mean:
1) Solo play - User has complete slider control over how he plays his game.
2) MP Online
a) Society Play - Users have the gameplay sliders set for them by the Admin of the Society. These are set as a minimum for everyone competing in the tournament. The one option being that if players want to keep their sliders, they can as long as those sliders represent a more challenging slider set, not an easier one.
H2H Online Play - Could either have an agreed upon set of sliders that both or all play - OR like above, have a minimum slider difficulty with the ability to play a tougher difficulty if you so choose.
c) TGC Tours and Tournament Play - Tournament director sets a minimum difficulty for tournaments, but users can choose to play a tougher difficulty. Very unlikely in a competitive environment, but it would give tournaments a different feel to them since there is variation in the difficulty of each one. Right now, all TGC2 has are 3 clubsets with some differences in challenge, but not a wide enough variety in shot outcomes and challenge for the users.
I don't think you are being "everything to everyone" by giving the user control over how he/she plays the game and what they get out of the experience.
EA failed with Tiger 14, not because they tried to be everything to everyone, but I truly believe that they did not endear themselves to their users with their changing stance on DLC courses every version and the franchise grew stale by the time '14 was released. I believe they wore out their fanbase with DLC courses. They hit a home run with '12 and the version where you could earn course DLC with coins by playing the game. The next year, they removed that popular feature. I also firmly believe if Tiger had a course architect for '12-'14, they would still be publishing console Golf game today. The fact that X1 and PS4 were already being hyped did not help Tiger 14 and I think EA waited too late to release Tiger '14.
