I'm currently re-watching the original Fullmetal Alchemist and Brotherhood together, and one of the minor, yet obvious changes I noticed is that Liore is in the middle of a desert in the 2003 anime, but surrounded by forests and hills in Brotherhood.
I'm assuming it was not originally a desert in the manga (since Brotherhood is supposedly closer to the manga). Is that true? Was it even specified? Either way, why did they make this change for the TV series?
