Thanks for showing me to that site. It's very helpful.

Just wondering if an OST was ever released for Paper Mario: The Thousand Year Door. One doesn't show up on the soundtrack list. This also seems to be the only Mario game that lacks one. I've tried searching with Google, but all that shows up are download links. I want to buy it.

Just want to say that backstory exposition (which is usually done via flashback, but for me, is preferably done through the character or other characters revealing it themselves) is extremely important to character depth. It explains why the character is the way they are and both makes them more realistic and more relatable, since it enables you to understand why they feel things and also know more deeply how they feel.

As far as best RPG stories go, I'd have to say that BoFIII and BoFV are my favorites. There's really an important message in both of them, if you bother to look into it.

For relaxing tracks, I'd go for:

Final Fantasy Crystal Chronicles OST
Final Fantasy VIII OST
.hack GU OST 1 and 2 (2 has more)
