u can use mic but no joystick or ps2 controller  

Answer 2

You can use a mic.  

You cannot use a joystick by default, nor can you use a PS2 controller.

If you install JoyToKey or other mouse/keyboard emulation software you can get most joysticks to work, but the game is not designed to be played that way on the PC.
