rules, there exist errata and FAQ files, to ensure potential rules conflicts between editions are resolved universally. In addition to the official rulesets, Games Workshop has also encouraged the writing of unofficial "house rules" by wargamers. As such, there have been a number of unofficial fan supplements and other supplementary material on the internet; the most notable of which was The Age of the King, made by The One Ring. Although some of its subject matter was later covered by official rulesets, it is still considered "the benchmark against which all others are measured". In many cases, supplements are written for areas where Games Workshop's licence does not extend, such as The Silmarillion. Legions of Middle-earth , Games Workshop released a new expansion entitled Legions of Middle-earth, centering on theming and army building. It is not a supplement or rulebook, as it contains no rules; instead, it provides army lists for players to theme their forces around, and scenarios which are designed to work in conjunction with them. However, Games Workshop also released supplement summaries online in conjunction with Legions of Middle-earth, so effectively a player only requires Legions of Middle-earth and the main rulebook in order to use the rules of the supplements.With the exception that the summaries do give access to a model's basic wargear, available "Magic" or the Movement rate. According to one review, the army lists would transform the game "from what has essentially been a scenario-based game that appealed mostly to collectors to a genuine tournament-compatible game system," although in this it "could have been a little bit more restrictive." Some of the miniatures for the point values listed have not yet been released; in this way, the book was not to become obsolete with future releases for some time. Variants and derived gamesAll at Sea is an adaptation of the rules for naval conflicts. The official rules were a modified version of the Warhammer Boat rules, adapted by Nick Davis and first presented in Games Workshop's White Dwarf magazine (US issue 295). The game's mechanics centred on boarding parties, with options for ramming actions and naval artillery in the form of ballistae and other siege engines. Model ships are built by hobbyists, just as normal miniature terrain, such as "great ships" of Pelargir, cogs of Dol Amroth and Corsair galleys. Game systems The standard game is played with two or more armies on a
