ZNDXIII

Quite frankly, Code Geass may very well be (in my opinion) the greatest anime to date. It's exceptional storytelling, theme-plot structure, voice acting, action, art style, and... robots, always for good measure. The main protagonist, Lelouch, vascillates between the great hero and anti-hero roles with ease (particularly in R2), playing on both Western and Eastern structure of a cartoon hero. The mechs, Knightmare Frames, are essentially below-atmosphere Gundams minus the incredible agility - so if the robots are your thing, you might not lose TOO much interest - though they're design, specifically the more advanced models, are much better. The power of Geass is the most enticing aspect of the fictional aspects, the highlight of the story aside from Lelouch's journey. I'd definitely recommend.
