Zeal is definitely the best part. I have a map of the Kingdom of Zeal up on the wall of our computer room (along with a map of Vvardenfell and Athas's Tablelands), and I wrote about the Mammon Machine not too long ago!

Laura Shigihara has a bunch of good music. She did the ending song for Plants vs. Zombies and the whole soundtrack for To the Moon, including this song.

She has a new game out called Rakuen (楽園, "paradise") that she did all the music and graphics for, but I haven't played it.
