one thing I would really like to see added to game features is aircrafts, and watercrafts.
of aircrafts helicopters would be really a plus I think, and not where you push one button to go up and one button to go down.
if anyone has ever played any of the battlefield series and flown the helicopters, this is the functioning of helicopters I would like to see.
W is accelerate, once accelerated enough you lift off, and then climb in altitude.
S is decelerate, which would slow down engine to lower your altitude
A & D would be rotor control.
yaw would be controlled with mouse.
so to lift off press W until lift off, then push mouse forward to lower nose of helicopter and move forward, push back on mouse would raise nose and level you off, or make you fly backwards. left and right of mouse would ofcourse tilt the helicopter left or right. and A&D would pivot nose left or right.

Please read the voting, page. This is already planned.(Its in features)
