Advanced Dungeons & Dragons. Role-playing game based on Tolkien's Lord of the Rings universe. Oh, OK. How old is that game? Is it good?
1st publication : 1974 as Dungeons and Dragons (D&D). In 1977, and "advanced" (more complicated) version appeared, named AD&D. More details regarding the RPG : http://en.wikipedia.org/wiki/Dungeons_&_Dragons
This game is the root of almost all heroic-fantasy games, like Lord of the Rings is the root of almost all heroic-fantasy litterature or movies.
Interest of the tabletop game depends mainly of the rule-master and of the players. I'm sure you already played an AD&D-complient videogames like "Dungeon Master" series, "Eye of the Beholder" series, "Baldur's Gate" series, "Neverwinter Nights" series, ... or all the old 80's games from SSI (Pool of Radiance, Realms of Darkness, ...)
