I'm not squeenix's PR, i'm not "excusing" anything, and neither is Square-Enix. I'm telling people why (from the standpoint of a writer) the game was developed in the way it was and what they're really complaining about. They built a narrative, and then constructed the game around the narrative, just like you build a TV show or a movie or a book or any other narrative medium. If you don't like the way it goes, then you're probably playing the wrong game.
The point I'm trying to make is that it would be out of place and entirely out of character for the protags presented in the plot to simply mill about in cities talking to people just because you the player expect them to. The developers likely saw this coming, and stuck to their guns regardless. Hell, they actually DID write in a completely random plot element just for people who like side-stuff (the mark sidequests).
I'm very impressed by Square-Enix for this game. It breaks genre rules and breaks them well. Unfortunately, some people (or a lot of people) simply can't stand the idea of the rules being broken, I guess.
You're idea that they wrote the plot to excuse game elements is almost certainly baseless and completely false, because frankly, that's not how it works.
thank god.
watch your words, Sixto. the JRPG Gods have smitten foolish mortals for less caustic statements.
