Eras would simply limit the maximum technology and the chronology of the universe. Players that start further into the timeline will see events that happened in the continuity of the story line where as earlier starts would have more freedom. But even those starting earlier in the game will see certain things happening anyways unless they are prevented (i.e. Palpatine will be cloned unless Byss is controlled by the Rebels, or Thrawn will find the Katana Fleet if someone else doesn’t first, or 30 years A.B.E. the Yuuzhan Vong will invade the galaxy).
