Elder Scrolls IV: Knights of the Nine

Gameplay
Knights of the Nine changes none of the basic gameplay of Oblivion; the basic design, maneuvers, and interfaces remain unchanged. As such, it is a fantasy-based role-playing adventure game. Players begin Oblivion by defining their character; deciding on its skill set, specialization, physical features, and race. Knights of the Nine is an example of open-ended or sandbox-style gameplay: the main quest may be delayed or completely ignored as the player explores the game world, follows side quests, interacts with NPCs, and develops a character according to their taste. Furthering the goal of open-ended gameplay, Knights of the Nine, unlike Bethesda's prior content packs for Oblivion, begins with no explicit prodding towards the newly introduced content; players must seek out and find the game's quest without external aid.

Plot

The Chapel was recently attacked; everyone there has been killed in a dark ritual. The player proceeds to consult a prophet near the scene of the attack, who is preaching about it. The prophet reveals to the player that the one responsible for the attacks is Umaril, an ancient revenge-seeking Ayleid sorcerer-king, who has escaped from his prison in Oblivion to destroy Cyrodiil. Umaril can only be defeated by the prophesized Crusader, favoured by the gods, bearing the relics of Pelinal Whitestrake, the man who originally slew Umaril, and banished his spirit to Oblivion.

The player then makes a pilgrimage, and receives a vision from Pelinal Whitestrake, who reveals the location of his tomb, which is beneath the lake surrounding the Imperial City.Inside this tomb, the player discovers the Helm of Pelinal's armor, as well as the corpse of Sir Amiel, one of the old Knights of the Nine. His diary reveals the location of their priory, which houses the Cuirass of Pelinal. Before the player can claim it though, he/she confronts eight spirits of the old Knights of the Nine, including Amiel, who had all given into corruption and been killed. They assist the player, who soon gathers all of Pelinal Whitestrake's relics. During each leg of the quest to retrieve the relics, the player meets a priest, knight, or pilgrim of faith, each of whom pledge to aid the player, each representing one of the original eight divines. After a final blessing from the prophet, to represent the ninth divine, Talos, the player leads the knights against Umaril's stronghold, defeating the Ayleid King, and then pursues Umaril's spirit, destroying him utterly. The player then wakes up in the Priory, with the knights believing him/her dead. After realizing that the powers of the gods resurrected him, the player rejoins the knights.

Production, release and availability
Prior to any announcement regarding Knights of the Nine, Bethesda had pursued a somewhat novel plan to distribute downloadable content through micropayments, priced from US$0.99 to US$2.99, instead of the more common practice of releasing expansion packs. The program was initially met with criticism by customers due to its alleged low value, but later releases—at a reduced price, and with more content—proved more popular. The releases, in addition to stirring controversy, raised questions regarding Bethesda's future content release plans, and as to whether expansion pack releases were necessary at all. In August 2006, one Bethesda employee wrote in a post to Bethesda's Elder Scrolls forums that the company had "no plans to make an expansion for Oblivion". Further questions were raised by a product listing found on game retailer GameStop's website September 11, 2006, listing a Knights of the White Stallion Expansion Pack for Oblivion. The game had a listed shipping date of November 21, 2006 and a US$ 19.99 asking price. The title was kept on the website only briefly—removed after gaming news site GameSpot sent Bethesda a request for comment on the product.

Knights of the Nine began its life as a supposedly "exclusive" quest for the PlayStation 3 release of The Elder Scrolls IV: Oblivion. Along with the confirmation of the PlayStation 3 release on October 9, 2006, some gaming news websites reported that the release would contain "a huge, exclusive quest" focusing on "a new faction, The Knights of the Nine". Some reports prefixed "allegedly" onto statements that the release would be exclusive.Suggestions of exclusivity, in any case, did not last long: an October 17, 2006 Bethesda press release announced that Knights of the Nine content was also scheduled for PC and Xbox 360 releases, eliciting commentary from Joystiq remarking on "how finicky" the word 'exclusive' had come to be, and Kotaku remarking on how "Oblivion PS3 content didn't stay exclusive for long... or at all". Other sites saw no incongruence in the announcement: GameSpot assumed that Knights of the Nine was simply the earlier Knights of the White Stallion by a different name, and 1UP.com had anticipated the move ever since an ING interview with Oblivion's Executive Producer Todd Howard, where Howard had described Bethesda's general aim "to have all our content available across all platforms"; the final announcement served only to confirm their suspicions.

The October 17 press release set November 21, 2006 as the North American distribution date for the Xbox 360 and PC versions of Knights. The European release for the Xbox 360 and PC was set two days later, on November 23. The European release was co-published by Bethesda and Ubisoft. On November 9, 2006, Bethesda clarified earlier statements regarding PC releases, declaring that, although the boxed retail PC edition of Knights of the Nine was set for release on November 21, the PC release downloadable from the company website wouldn't be available until December 4. This caused some consumer complaints, for although the Xbox 360 release was available on the Xbox Live Marketplace for 800 Microsoft Points (the equivalent of US$ 10.00, or GB£ 6.80), for the time being, PC owners had only the US$ 19.99 boxed retail edition of the game. The increased price of the PC's boxed retail release (The Elder Scrolls IV: Knights of Nine Oblivion Downloadable Content Collection) resulted from its inclusion of Oblivion's other previously released downloadable content: Horse Armor, The Orrery, Wizard’s Tower, Vile Lair, Thieves Den, Mehrunes’ Razor, Spell Tomes, Fighter's Stronghold & a series of dashboard themes and picture packs. Such content was not included in either the downloadable PC release, the Xbox Marketplace download, or the PlayStation 3 edition of Oblivion. The downloadable release was ultimately issued on December 6 at the price of US$ 9.99. According to IGN Entertainment's GamerMetrics, a service based on compiled visitor activity information on IGN's website, the pack was the fourth most anticipated release of its release week, following Tom Clancy's Rainbow Six: Vegas, Superman Returns and College Hoops 2K7.

Reception
Knights of the Nine was generally well received in the gaming press. Metacritic, an aggregate review site, scored the PC version of the game with an 81 out of 100, and the Xbox 360 version of the game with an 86 out of 100. GameSpot recommended the game for its value; although it made few improvements over the basic Oblivion experience, Knights of the Nine provides "a good day or two's worth of questing for a low price". Similar comments followed from GamePro, who found that the "polish" and "affordable price" of the pack excused the fact that the pack's content "doesn't really change [Oblivion's] gameplay".

Eurogamer praised the game for its memorable plot and new, unique content. They concluded that if "more of the same is what you're after, you can't really argue with what Bethesda's served up for its hardcore fans." The review encouraged caution nonetheless: for if consumers were to fully accept individually priced content releases, Bethesda might just begin charging for all its quests.
