The ps3 doesnt even use mouse and keyboard for controls. Ive seen devices trying to imitate the mouse movement that are available for ps3 tho, but they are not very smooth or accurate.
If your Pc is that old then i doubt itl even play this game smoothly in the lowest settings, but thats just a guess as i have no idea what the system requirements are.
But i think this game should be played in max graphics to trully enjoy it , so you might have to go with the ps3 version or build a new pc capable of maxing it.
