I recently watched the Rage of Bahamut series and enjoyed it immensely.
It is directed by Keiichi Satou (Tiger & Bunny, a bunch of Mobile Suit Gundams), with Hideki Nakamura (Berserk The Golden Age Arc I, II, III) as the Art Director and Naoyuki Onda (Ergo Proxy, Berserk The Golden Age Arc I, II, III) as the Animation Director. They`ve all worked on so many awesome projects that it was difficult to choose which ones to reference. The art and animation are top notch. If you're looking for a Dungeons & Dragons fix, this could be it. It's a solid fantasy story with a sprinkle of western themes. I absolutely loved it.
