This is true, but it is possible to connect to a PS3 or a PS4 a mouse and a keyboard too.
I dislike Xbox and PS controller for FPS games.

YES YOU CAN connect it but there are ALMOST NO GAME that support the mouse and keyboard input . the only thing i remember the console peasant game that have a mouse and keyboard input is csgo for ps3

and not only mouse and keyboard is much better for fps game but i think for all genre it is much better . mouse and keyboard have the flexibility of a touch screen and a tactile feel like controller and even better when using a mechanical keyboard . but with mouse and keyboard you get thing that other control method doesnt like precision control for example
