Whatever else might be said about it, there is no doubt that Terakh is unique. See the definitive pictorial overview of the game and its unusual components here. It's a sci-fi themed war game on an abstract map with dice driven combat and magic cards that modify and affect outcomes.
The game designer suggests the game is a hybrid of Risk and Magic: The Gathering, but most players seem to agree that this description is inadequate. Some have suggested that as a light, quick game focused on combat that rewards offense it is closer in spirit to Nexus Ops. Others regard it as a blend of war-game elements (particularly the movement and dice-based combat), mixed with elements of an abstract, mixed with elements of Magic: The Gathering.
