Anime Suggestions: Sci-Fi/Mecha

       Aldnoah.Zero is a an anime about a future where humans discover that Mars once held an extremely intelligent civilization. The leader of the people that discovered the technology then founds an empire based around said technology. War arises between The Royal Vers Empire of Mars and Earth. The show addresses the war from both sides in an interesting way. I won't spoil anything, but its first season goes out with a resounding bang. This show also has a lot of good action sequences.
