Stat maxing comes toward the end of the game in Chapter 10. We'll be more than strong enough to get through the story no problem, and we'll do a very efficient power up right before we need the extra power for the super boss and the ending on Hard Mode.
Great!! I have to complete it too.! This is gonna be awesome! (I have one doubt, I played some time, and that time, I "grinded", I fought redoing missions for level up early in the game, but I heard that this is bad idea because of "I don't know what" stats or something like that, and I'm worried about if I just I have to start it since the beginning, so.... It's true?)
You can grind in the early game if you want to, but it isn't really necessary. Before we fight the last boss on Hard Mode, we'll have to do some grinding to get stronger, so the choice is yours. Feel free to replay missions as much as you want to get stronger and level up materia. That will only make things easier going forward.
