Man, the helicopter controls and maybe even moreso the camera make me want to hunt down Volition programmers. The helicopter races and the higher levels of the helicopter assault activities are just a constant battle with both the controls and the camera. It's the complete opposite of _fun_.
Which isn't to say that most of the game isn't fun however.
At least half of the problem would have been solved had there been a cockpit camera in the game.
Heli Assaults and the second half of Corporate Warfare are still unfinished for me due to the helicopter pissing me off in new and creative ways midway through a task (I swear half the buildings in Stilwater have helicopter attracting magnets in them).
Saints Row 3 cleaned up vehicle controls considerably, and copters and planes are easy to use... so of course they decided to remove races entirely.
