Yeah, it's really too bad that there aren't many people who know about Planetes. I just wanted to add another anime that also surprised me quite a bit: Wolf and Spice. An anime that's mainly about economics being so fun and interesting? No way! But it's true. Though I'm admittedly more into it for the romance between the two main characters, the merchantry (awesomely made up word) is actually quite interesting. If you can get your hands on it, totally recommended!
