Birth by Sleep Theory on the Leveling System of Kh

Theory 1:
Nomura said that the leveling system of BBS would be different as in it would be more of a "growth" system...naturally, because we havent seen anything like it it would confuse us and leave us cursing at our computers while we read the interview...Well I've been wondering and cursing ever since and now I've started to form some sort of idea...

So, we know that BBS takes place 10 years before Kh2 and 9 years before kh1 right? Right...
and Nomura said that it would be some sort of growth system right? So I was wondering if the three protagonists (Terra (Tera?), Ven, and Aqua) start the game off as young teenagers (or kids O.o) and then grow to become adults...or at least a little older...while they grow up, they become more powerful and skillful, gaining new techniques and new attacks. Why do I say that? Think about it! In the magazine scans it shows that both Terra and Ven have very long hp bars. A common trend in kh2 is that the further u are in your game, the longer your bar is, until it fully curves around your character's picture and moves down. Maybe Terra and Ven are older by then...

Still, I have problems with this theory of mine...it works and then it doesnt work. If they do the game "naruto-style" where ninja's in Naruto start training as Ninjas when they are like 7-10 years old then it would work in BBS where Ven is a 7 year old keyblade apprentice. (7+9=16 and 9 is the amount of time that passes between BBS and kh1 and Ven looks like hes 16 years old)

Idk...I think my theory is head-on for the most part...=/

what do you think?

 

I think, that BBS leveling system is similiar to KH2 Bonus levels (You will level up, when you have completed some kind of event).

 

First, Nomura said BBS takes 10 years BEFORE KH not KHII meaning that BBS is 11 years before KHII.
Second, you might have a reason the more older the better the growth explaining Terra's long bar but at the same time we don't know when we will reach that area either in the future or in th past.

 

Maybe it's like that system in Final Fantasy II. You know, where each time you take damage, your max HP goes up, and the more you use weapons, armour and magic, the stronger they get.

 

I would think the growth would be like FFVI, the stat depeneds on the weapon equiped (keyblade), for example, if you level up while having Star Seejer equip, you will gain +1 Magic Point when leveled up.
