I don't think head to head ever stopped working..
The lobby doesn't work though, correct?
(I don't have a PS4 anymore otherwise I'd check)
It gave me the option of head 2 head, which works fine, also i was able to play daily and weekly events and join a game with 3 other randoms. All in all i don't know what they actually ceased doing here?
On a game play note i was amazed at how easy tour mode is, it's hard to miss a fairway at the hardest level. After playing the game from cold i won my first tour / career event with a score of -30 6 shots clear of 2nd. The only other option to make this harder was turning off green grids, now i have come right back to the pack and can enjoy it...for a while at least.
The game does side hill lies really well and you have to rely on pure visual to discern if it is on a side hill lie, some are more obvious than others. Putting is a bit too simplistic from a mechanic standpoint, although its not too easy, especially with no grid.
Even in tour pro mode the game has a marker that you can pull in or push out that sets club distance, this also makes it a bit too easy, you don't have to rely on partial shots even though the game appears to play partial shots really well, that's a shame.
Overall its something different that has a career mode ( way better than TGC career ) but it does make you appreciate the controller swing in PG, wish i could take that and plant it into Rory, that would be great.
