When you first leave Kalm and step out into the big open world of Rebirth, you might be tempted to run off and start exploring. By all means, give into that urge, but know that many activities won't properly unlock until you meet up with Chadley at Bill's Chocobo Ranch.
While the fundamentals of the combat system are essentially the same, Synergy Skills and Abilities are worth getting used to sooner than later. Skills can be activated holding R1 and selecting a face button.
