That seems to be the general consensus, but I honestly can't agree. Uematsu is an amazing songwriter, up there with the best in the business to be sure, but he has plenty of limitations, and frankly I think he relies too much on emotional and even outright sappy stuff. No
Final Fantasy soundtrack other than
FFXII is in my top 5 for this very reason. I really do enjoy a lot of them, but I still find that problematic when taking them as a whole.
Actually, it's recently come to my attention that I feel exactly the same about the stories. There's been talk here about how some past stories have been better because there was more emotional context and more complex relationships between characters, but honestly, I'm feeling now that they rely way too much on those relationships to make the surrounding events interesting. And it seems like it's the same 4 archetypes used over and over, which leads to characters that end up feeling like toys to me in the end. I loved the hell out of
FFX (for very different reasons than
XII), but I wanted to punch Titus and Wakka in the face for at least half of their screen time. It was a great game, and I did like the story, but 95% of what was driving me was the character relationships... I really didn't care how things turned out in the end, which is probably the main reason I never finished it. I'd type more about the other games, but you can probably figure out what my misgivings are if you'd played them anyway.
I guess what I'm trying to say is that while in some ways less emotional,
XII feels like by far the most mature
FF I've played. Characters actually seem to stand for ideals and I actually care about what's happening in the story because it feels like there's real consequence there (the superior localization and huge volume of contextual dialogue with minor NPCs helps this a great deal). Like everybody else, I think a few more ties between characters and a little more poignant emotional stuff would definitely make the game much better, but unlike everybody else, I think if you're going to end up lacking something, lacking the sap is definitely preferable for me. I might change my tune if I ever felt like the emotion was conveyed well enough (like Jackie's relationship with his girlfriend in
The Darkness), but... eh. Maybe some other time.
Anyway, sorry to go off on a tangent there. I'd just been thinking about that for a few days when I realized that I'm actually really interested in seeing the end of
XII and haven't really cared much with some of the others. The same formula applies to my thoughts on the music, though. I like Uematsu's stuff, but I think he fails at doing anything for me as soon as he moves outside his comfort zone, where Sakimoto can consistently move me to tears even when he isn't doing something "emotional" (like the Westersand music... I tear up or even cry whenever I listen to that song outside the game).
Um... *Cough* yeah. So as for your loot question: selling everything will get you in trouble. In fact, you probably already sold at least one item that relates to a later quest... though I think there's only one. The Giant Serpentskin (I think) is used for something, though I can't remember exactly what. The way it works is that if you sell loot related to a recipe (i.e. ItemA x1, ItemB x2 = ItemC), it keeps track of that until the bazaar item is unlocked for purchase. So you might sell 99 of ItemA, but if you then sell 2 of ItemB, 98 of ItemA are essentially "wasted" in terms of unlocking another purchase. In other words, if there was another recipe along the lines of ItemA x 33, ItemC x1 = ItemD, but you'd sold 99 of ItemA to unlock the prior recipe, then you're going to have to go farm another 33 of ItemA in order to unlock the latter recipe.
It's a little confusing. I think I said it here already, but use
this loot FAQ to at least get an idea of how it works if you still aren't clear. And frankly, using a guide is pretty much necessary if you actually want to plan this stuff out, and even when using one it can be confusing as hell. The best use, though, is figuring out what stuff is really rare or useful and what loot is "one shot" stuff that you can just sell off as soon as you get it because it's only used for a single recipe or whatever. I highly recommend that. You can avoid FAQs for all other elements of the game, really, but if you want to understand the loot stuff, a guide is a must.
FF games have often been the type of thing where you miss tons of stuff unless you have a guide to tell you about it, and
XII is no exception when it comes to some of the more obscure things (you can fish, but good luck ever figuring out how to unlock the minigame without a guide, and it is absolutely guaranteed that you already can't get the game's ultimate weapon because of something you'd never know unless a guide told you -- don't feel bad, I think it happened to every single person who played the game the first time unless they were being cheaty and reading guides up and down).
