Because they're too used to the mouse. Just play with it, get to know the mouse and you will experience much better gaming and all around general usage. All you gotta do is find a game that requires a lot of movement and then use the Imperator and in no time you will find yourself mastering any fast movement game, or any game for that matter. In some games that have joystick usability I find myself having better control with the Imperator vs. the expensive joystick.
yo dood, Is it possible to assign 3 key presses to one button? For example, in Battlefield BC2, when you shoot with the right mouse button, you aim and spot all at the same time. Right mouse button does 3 things, aim, shoot and spot. Thanks.
