I have been playing Golf games since Intellivision Golf(1980), Atari Golf, Leaderboard (1986), Mean 18(1990), etc and have watched them evolve over the Last 30+ years. My favorites would be Jack Nicklaus 4/5 & TW06w/course creator ( which i still have ). I stopped around TW06 and have not found another game I liked that had a Course Creator.
Compatible with Windows 10 64 bit.
Yes
The swinging/animation of the the club and reaction of the ball whether Driving, Chipping, Putting, etc..
New player animation WIP
Real ball physics is a must not instant hole in ones, strange bouncing, etc....
PG uses real time flight/spin physics which is always being refined. Ground collisions still WIP.
A full array of shots Fade, Draw, Punch, Stinger, Chip, Pitch, etc with any club I want would be nice. Being able to control tee height, ball placement in stance, controlled club face contact with ball high, low, left, right...
Shot types and shot shaping catered for. No tee heights as yet. No stance positioning implemented yet.
Atmosphere would be the next thing I need to feel like I am on the course trees moving in the wind, realistic weather, overall graphics, sound, etc..
Speedtree trees move with wind. PG comes with dynamic weather based on specified location. Graphics and sound WIP.
Full character customization meaning face, body, hair, clothes, shoes, clubs, balls, skills ,etc...
No idea if PP are going down the old 'TW Character' creation route.
Reliable Servers to play on would be good as well with game rooms, settings, stats, records, decent UI, etc..
Some folks have issues with multiplayer connections, some don't. Lobbies already available, full release will see player stats, records etc. UI still being worked on.
Full Course editor and creator that's simple to use.
Course Forge (and Terrain Forge) are powerful and reasonably easy to use. The terrain editing tool is Unity 3D itself, so a knowledge of that application alone is recommended. Course Forge is just an asset package add-in.
The ability to practice offline Driving and Putting would be a plus.
Game comes with a Driving Range, but as yet no putting green. Practice putting currently done on course with mulligans enabled.
And of course being able to choose complete gameplay settings for match play
Multitude of MOP's (Modes of Play) with Stroke, Matchplay, Skins, Team Games, Nearest Pin, and soon to be introduced a new Challenges mode.
I am sure I can come up with more just sitting here, but those are probably some of the major things I am looking for.
