I tried the whole kb mouse thing with the demo... wasnt happening.
I did the whole keyboard and keyboard thing... and that got old but it was very effective. Hence why my jet kd ratio blows so much ass.
Finally got a joystick, nice and cheap saitek st90 14 bucks, no twist action, still using wasd for throttle and rudder. Got sick of having a sore left hand and decided to step my game up.
This joystick has a lot of bugs but once you iron them out pretty much its butter I can perform almost 60 functions at the tip of my hands using the joystick.
chat, eject, parachute, hat view, map resize, map window, talk to the commander, open up the main radio window and spot an enemy while im flying. There is just a lot you can do With this joystick its amazing, and the trottle helps you hover cap flags in a helicopter or pull off some crazy ass stunts that you cannot pull off with a mouse. Its just not accurate enough.
The only benefiit a mouse will give you over a joystick is that you can fire rockets in a helicopter more in a more stable focused pattern.
But 100 dollars is quite excessive.
