TIE / X-Wing should be doable with a game pad, no?
I used to play with a gravis gamepad occasionally, but you needed a keyboard to hit all the extra stuff.
Actually, my flight stick was a 2-button stick, so I kind of always needed the keyboard. X-Wing had a ton of controls, although luckily most weren't necessary.
That game was so fucking cool when it launched. I still have my copy, boxed.
