First map come to mind is Lou Yang. I like both the town and field. Easily accessible (can I say great location like in real estate?). Nice landscape, ancient style music, yummy exp from soil. Not so dangerous. Love it more without the annoying mantis.
The dungeon is a bit too dark but what you expect it's a tomb. It's still nice.
(I think we have a thread like this some time ago but let's hear what the others have to say.)
