World of Warcraft
"World of Warcraft" was first announced by Blizzard at the ECTS trade show in September 2001. Released in 2004, development of the game took roughly 4–5 years, including extensive testing. The 3D graphics in "World of Warcraft" use elements of the proprietary graphics engine originally used in "Warcraft III". The game was designed to be an open environment where players are allowed to do what they please. Quests are optional and were designed to help guide players, allow character development, and to spread characters across different zones to try to avoid what developers called "player collision". The game interface allows players to customize appearance and controls, and to install add-ons and other modifications.
World of Warcraft: Rise of the Horde
World of Warcraft: Rise of the Horde is a novel by Christie Golden set in the Warcraft Universe. It was published in December 2006. Golden also has a commitment with Blizzard Entertainment and Simon & Schuster to write a StarCraft trilogy. Originally presumed to be the sequel to her previous 2001 book, , it depicts the draenei's escape from Argus and the rise of the Horde, following their shift from a shamanic race to a warmongering one. The book features major Warcraft characters, such as Durotan, Ner'zhul, Gul'dan, Orgrim Doomhammer, Kil'jaeden, and Velen. The story tells of how the orc clans and the noble draenei slowly become enemies due to deception and arrogance, and shows the downward spiral into which the orcs are thrown, and explores the role that demonic forces play in the Horde. It also expands on the origin of the Burning Legion, and the events preceding the first game of the Warcraft series.
