From the overview:
The dice building game engine was pioneered in WizKids Games 2011 release Quarriors! designed by Mike Elliott and Eric M. Lang. Similar to deck building games where players collect a resource to purchase better cards to add to their deck— in a dice building game, players are collecting dice. In The Lord of the Rings Dice Building Game, players must work together to assemble an army of dice representing brave Men, battle-ready Dwarves, wise Elves and stout-hearted Hobbits and muster their troops against the forces of Sauron. But beware — some may be tempted by the power of The One Ring and become corrupted by evil!
