It just seems inevitable with success comes increasing fans and popularity and increasing expectations. Ever since FF7 really the series has been burdened with a need for high-octane emo-ish protagonists with a stylish haircut. Ever since X the series seems to have assumed we need train track map and level design with lots of awesome I win buttons and stuff.
A lot of times people seem to want the same thing, basically, so the expectations create the repetitive content.
Money is just like if someone spends 50 million dollars on something, they aren't going to go oh hey that's a crazy killer clown type character with no apparent morals or justification for anything he does, we can't have 'him' in the game (even if he's the antagonist). Would a Kefka type character be allowed in a later Final Fantasy? No, some MBA or whoever would object, saying it's too far outside the norm and some hapless gener-O-villain would be put in their place. Never mind that's how the FF brand (which generates money in the present time) was created in the first place.
Anyway, I'm not really referring to any one person's expectations (such as yours), it was just more of a general thing. And really, there probably something to be enjoyed in that game at any rate.
