Not everyone is concerned with being "deep"; they're merely concerned with doing whatever it is they want to do. This shouldn't be looked down upon for not being more complex; it's the operative mechanism of all lifeforms, and it's fairly simple.
Deep and complex aren't the same thing either. For something to be deep, it would have to make you really think about the situation presented and what it means to your own existance. I don't think any game, FF or not, constitutes as "deep".
