XWA is best enjoyed with a joystick that supports rolls. My joystick is probably about 10 years old at this point, but it's a Logitech (and was $50 when new) so it's solid even now (and thank God it came with a USB adapter). It supports twisting the stick left and right to 'roll' the craft, and let me tell you the difference it makes in XWA gameplay is tremendous.
It's hard to go back to XvT where that functionality is not supported. Rolling makes for some great evasive maneuvers when avoiding pesky TIE's.
