PG have made a good start by adding this desirable functionality. What it needs IMO is the ability to do 2 extra things (both things that Links 2003 did brilliantly) to really take it up a level.
1) The ability to play with another players tournament REC round. By all means disable the behind the view camera and just have the sideways camera. Disable information re what club friend has used (even distance, elevation etc) i.e you would just see the screen with no additional info. Would really add extra immersion.
2) The ability to sit back and watch 2 (or more REC rounds) as a spectator. Yes I can select a round but I have to play along with it. Would be nice to have this option when you just want to sit back and relax.
On another note , can 2 or more people play online tourney rounds? Not sure if I have seen a route to this in the options. Or is this something we cannot do at present?
