The One Ring Roleplaying Game is set between the years of the Quest of Erebor and the War of the Ring. The default setting for the Middle-earth Role Playing game (MERP) was the middle of the Third Age (circa 1640). Decipher's The Lord of the Rings Roleplaying Game was, like TOR, set between The Hobbit and The Lord of the Rings, but was meant to be versatile enough to accommodate adve ntures anytime from the First Age to the Fourth.
