SPI boxed compilation of their three Middle Earth games: War of the Ring is the big game, and Gondor and Sauron are smaller ziplock/folio style games. The games are primarily two-player hex-and-counter wargames.
In War of the Ring, great armies battle while individual characters from the books control the fate of the One Ring. The "character game" can be played separately, to reduce playing time and complexity, and there is also a three-player scenario.
Gondor is based on the siege of Minas Tirith along with the battle outside the city gate as depicted in J.R.R. Tolkien's novel The Lord of the Rings.
Sauron is a simulation of the Battle of Dagorlad, from the 2nd Age, between Sauron and the forces of the Free Peoples (elves, men, and dwarves) outside the main gate of Mordor.
