I've been re-watching Last Exile on the AZN channel. I still think it has to be one of the most underrated, underappreciated anime ever made. It's such a wonderfully nuanced story, and a completely fascinating world. In fact, the "world" of Last Exile is so solid, it reminds me almost of the worlds of Bladerunner or Dune. A setting so foreign, but so powerfully and completely realized that you have no problem buying into it.
It makes me want to go back and finish
Pinwheel Libertines. The Guild is oh-so-fascinating.
