[quote name='ddrpower']Since this seems like a popular topic, I'm going to ask the same question that I ask in every other topic but never get a straight answer to:
In the game, as you play sidequests, your "battle rank" goes up, which makes the enemies more difficult to scale.
In the 360 version, I heard that doing all of the sidequests scales the enemies to the point where the game is extremely difficult to complete.
The PC version supposedly alleviated some of the scaling, but is the game still difficult if you go out of your way to be a completionist?[/QUOTE]
I can't answer that specifically but you are right that, in this game, the enemies do scale according to your battle rank (BR). The difference between this and say a normal level in another RPGs is that you don't always gain stat upgrades for each battle rank you obtain.
Early on, the game vaguely states that the more risks you take, the more rewards you get. I think a lot of people assumed that the game specifically means loot. While this is true, it really means that you get more increased stats for winning battles the harder they are (such as fighting 4 groups of monsters at a time instead of just engaging with one).
I'm not sure what the game's formula is for increasing the BR, but by challenging yourself, you can essentially gain more stats while keeping your BR really low. This in turn actually makes the game easier because, as stated, the game scales the enemies to your BR, not your stats. I've heard stories of some players actually beating the game with greatly varying BR (the difference of say 20BR and 100BR).
So I guess to answer your question, as long as you make an effort to challenge yourself in the sidequests and prevent your BR from increasing as much as possible, the difficulty won't be so much a problem.
