Okay, so, I hate using the keyboard for first-person games. WASD is nothing but a d-pad that requires three fingers to operate, and a joystick feels much better. But I love the mouse for aiming.

Lately, for first-person games, I've been using a combination of the PlayStation Move navigation controller and the mouse, and it's been beautiful, but I have a problem with Thief and Thief II: My fourth and fifth mouse buttons -- the ones on the side that my thumb can easily access -- aren't recognized. Only left, right, and middle click work. Is there any way to get those extra mouse buttons to be mappable?

Hates WASD?

Blasphemy!

Besides how do you play Thief without a keyboard as it's not a typical FPS. Between all the different ways to move, weapons, gadgets, etc etc you'd need a mouse with 40 buttons on it.

Okay, that works. After I read your comment, I searched for mouse mappers, and I found X-Mouse Button Control, and it's working fantastically well. Thanks for the tip! PlayStation Move navigation controller+mouse, my friend. Best first-person control scheme I've found on the PC so far. :D I get the single-thumb, all-speeds movement of a joystick, but the precision aiming and speed of a mouse. Plus, the navigation controller has a ton of buttons that are all supported by Thief (using MotioninJoy, of course).
