A keyboard is good for three video game genres: MMO, RTS, and Surgeon Simulator. For everything else, WASD is a horrendous d-pad that requires three fingers to operate and is used to navigate a 3D space. My PC controller of choice? Mouse+PS Move navigation controller. Yes, I'm dead serious.
The nav controller replaces the separate keyboard keys for movement, giving me a complete 360-degree movement system using just the joystick with only one thumb, while maintaining the precision aiming/cursor movement of the mouse. I've actually tried to go back to the keyboard for games like Half-Life 2 and Metro 2033, and I just can't. And don't even get me started on the original Thief games, which are carpal tunnel sources if you use the keyboard with their three million movement keys.
So, there we have it. I hope I made these interesting enough!
