Dragon Age: Origins is a beautifully rendered fantasy role-playing game with medieval European visualization for the game art direction. Combat is bloody and gruesome, filled with spraying blood and decapitation, but also stylized with special finishing blow animations. The game has various Downloadable Content adventures, items, and small expansions; and one major expansion/sequel, "Awakening".
This page of fantasy game art from Dragon Age: Origins features the Circle Tower -- once upon a time known as Kinloch Hold, but later deserted and now taken over by the Fereldan chapter of Circle of Magi. The tower has several floors, as well as a basement repository of artifacts and natural caves used as storerooms.
The last set of screenshots shows the tower tainted and in disarray from demons and abominations during the Broken Circle quest.
