Tanken Driland

A group of travelers set out on a adventure. Ridding the world of a mysterious force.  

It's both for children and really interesting. It's for those who love childish anime. 

It's pretty similar, especially DAT design. 

Deltora Quest was very much written as an "RPG Book", basically the fact the story is told as how a game would play out (and it later had it's own game in Japan). Driland is based off an actual mobile game for iOS and Android. The two share the similar feel of the impending evil that is threatening the land, the going on quests for treasure, the party members, the monsters, the everything you'd find in a videogame feel. If you looking for anime that feels like it is based on a game these both have that same feel. 

Both of these Anime feature females who go on an adventure to break away from what they are expected to become. The story also has a fantastical element to it. 

Both main characters dream of being Hunters without understanding what that all entails. 

Both Anime have the concept of "Hunters" people who go after relics. Hunter x Hunter is geared more towards a male audience while Taken Driland is geared more towards a female audience. Both characters though set out because someone inspired them to become Hunters.
