Druaga no Tou: The Aegis of Uruk

Both of these titles are fantasy with rich detailed worlds and fun characters. Tower of Druaga is over all more serious then The Slayers but it has its share of silly funny episodes. Tower of Druaga is based on a video game series and The Slayers has had video games based on it.
They're pretty much of the same genre; they're fantasy adventure animes with comedy. Though Druaga is more serious, it still has its own comedy moments. Both follow the adventures of a group of heroes on their epic quests, and are set in fantasy worlds that have many classic fantasy elements, suchs as mythical places, dragons and other fantasy creatures, and swords and sorcery.
