The Lord of the Rings: War of the Ring is a 2003 real-time strategy game (RTS) developed by Liquid Entertainment, the makers of the previous Battle Realms and its expansion, Winter of the Wolf, and published by Sierra Entertainment. Set in Middle-earth, it expands upon the events of the War of the Ring as told in The Lord of the Rings. Unlike the later The Lord of the Rings: The Battle for Middle-earth by Electronic Arts, War of the Ring is based solely on the books, not on the films by Peter Jackson. Thus, characters such as Frodo and Aragorn look and sound different from their counterparts depicted in the films.
