I have being playing SAN for a year and I have played the landings in the mini games over 5,000 times. The other mini game is the plane alignment to gate. I have seen the computer do it lining up the planes into the gate area but I never get a chance to play that mini game.
Regardless if the airport is small or not, or the number of planes I own, makes any difference.
SAN is my favourite airport game and I very much like to see the second mini game back into SAN airport.
