Adolfo,

What I've found is, some tend to always be the same, while others change.

If you want a "true" Random Number Generator.  Use something like a free
running clock that stops when you get some user input.

ie

Loop                            ;  Wait for Input to Start/Get Random Number
  incf   Random
  btfsc  PORTA, Button          ;  Drop out of the Loop when Button's pressed
   goto  Loop
