Is the game 320 blocks?
If so, this content wouldn't be able to fit in the game.
I love how people begged and begged for DLC 2006-2008.
We get it, and everyone complains.
Its OPTIONAL, no one is FORCING you to buy it.

Are there any bundles of content?

Now, I don't believe that this content is priced appropriately but I have seen companies in other areas price individual "items" at a very high price to create value from bundling it together. Basically, if you take 10,000 points worth of content and sell it for 2,500 points people see more value in it than if you just sell that content for 2,500 points on its own.

While it's expensive if you buy all the DLC, for 10 bucks, that core game is a steal. Also, don't bash Square-Enix on pricing; the FF4-After Years stuff is of amazing value. Each story chapter (2.5-3.5 hours so far) costs 300 points, and that is without the bonus quests you can do after completing each chapter.

The previous version was $15. This version is $10 - which is 33% less. If the game takes around 6-10 hours to complete like the last one, I'll be very happy!

I loved the last version and didn't buy any of the DLC. I'm thinking about doing the same thing again, especially since Square has lowered the price so much.

Who in their right mind pays for "cosmetic" DLC. I'm sorry but those guys are losers, big time.

I'd say the Japanese, but you wrote "In their right mind".

The did the same thing with the first game, and I didn't really feel cheated. I'll get this one as well whenever they announce it for NA.

^this. I won't be surprised if the $60 FFXIII lacks a ton of content even as far as bonus dungeons that would  only be accessible in the $90+ CE.

The Clothing apparently have in-game effects, so apparently none of those are "just" cosmetic. Though I still think it's way too expensive.

The first one also had quite a bit of DLC, and in total, it cost more than the game itself: 2500 points while the game was 1500.  There were a few things different that made it seem less a rip-off. 

1. There wasn't as much DLC (13 vs. 16), and individual items cost less than the ones here; the most expensive King DLC was 300 points (there was an 800 point one, but that was for three items), while the most expensive Dark Lord DLC is 600.
2. The content was released over time, so we didn't see this huge list of paid add-ons when we bought the game, so it never felt like they were gouging us; unless you only recently bought the game and see the full list of content.
3. Also, by releasing content alongside the game, it makes it feel like this is withheld content, that it was ready to go with the game, but was taken out for the explicit purpose of making people pay more for it.  If the DLC came out a couple months down the road, then it would seem like the developers put out a complete game, and are spending extra time making more content for it, and of course you're expected to pay for that.
