At first glance, Drakensang: The Dark Eye looks like The Witcher, or perhaps Neverwinter Nights 2. It draws its complex plot, art design and deep rule system from a Witcher-y European RPG playbook. You create a character from the ground up, gathering 4-character party to level as you please (along with a slightly clunky interface for controlling said party) as in NWN 2. While both of these comparisons are valid, Drakensang sets its own standard, moving in a different direction from its predecessors-but it's not exactly cutting edge either.
