Speaking of feedback..
@MikeJones: Got any thoughts so far since you bought the game and presumably have tried it?
I've not had time to dig deeply but here are some of my thoughts so far:
Character creator and animation - The creator seems fine but it's nowhere near as powerful as others I have tried so I found it a little frustrating to get a 'look' I was happy with. The clothes options are great and I found myself in the store spending my credits on different outfits which I didn't expect so full marks there. Swing animations seem unchanged from TGC2.
Interface - only dabbled with private rounds so far and everything seemed to work well enough. Again not huge changes in the way courses are selected but a huge improvement in that you can now customise the playing settings. TBH This is long overdue and makes it possible for me to enjoy the game as putting on the higher speeds is just so unrealistic to me I have to dial the greens down to slow or medium to have any resemblance of what I see IRL. I've been using soft ground conditions and very soft greens but I haven't played it since todays server patch.
Physics - ball flight still seems 'off' as with the longer clubs the ball seems to visually go too low. It may be some odd glitch with the camera FOV etc making it look like that but again it's hard to correlate what I see on screen with what a ball flight looks like IRL. I've been using the mouse swing so far and have made no efforts to hook up a controller yet. The digital on/off aspect of the mouse movement as opposed to something more linear was a bit strange at first but it's not too bad once you get used it.
Graphics - courses look ok, certain times of day and angles look great and others not so much. I like the SSR and refractive water and especially a thumbs up for the way the ball leaves a trail behind in the sand when it rolls into a bunker - that's very cool. Sky domes look poor IMO and they could perhaps have come up with something better.
That's about it really so far but I'm sure I've barely scratched the surface of the game.
PS when I first installed it I had crashes every few holes especially when using the shot shaper or changing shot type. Recently though that's not been a problem so perhaps something got fixed in the patch.
