There were two April Fools jokes done by Blizzard in 2008. One was the announce of WoW for consoles.
For the official website:
"Paris, France. -- April 1, 2008 -- Blizzard Entertainment, Inc. announces its long-awaited return to console gaming with World of Warcraft: The Molten Core™, a spinoff of the 40-person raid dungeon from its award-winning massively multiplayer online role-playing game (MMORPG), World of Warcraft®. World of Warcraft: The Molten Core will allow players to experience the excitement of the hit raid dungeon in a completely new format, with new challenges and new rewards.
"Blizzard got its start in console gaming, and we've always been excited about returning to this arena," stated Mike Morhaime, CEO and cofounder of Blizzard Entertainment. "Additionally, we've wanted to reintroduce the 40-player raid dungeon experience for some time. With World of Warcraft: The Molten Core, we're able to do both."
World of Warcraft: The Molten Core will include single-player and multiplayer versions, fully loaded with nine different shapes (and possibly colors) representing the current World of Warcraft character classes. A future expansion will introduce a tenth shape, representing the death knight hero class. Blizzard also plans to include a full-featured voice-chat system, as well as a fully customizable user interface that allows players to personalize their joystick button with several different functions. A free attunement cartridge rounds out the offering, providing instant access to the complete World of Warcraft: The Molten Core entertainment experience.
Blizzard's World of Warcraft: The Molten Core Collector's Edition, also announced today, will include tinted cellophane TV overlays, further increasing the array of colors available to players. Additional Collector's Edition features, as well as details on the upcoming World of Warcraft: The Molten Core beta test, will be revealed closer to release. World of Warcraft: The Molten Core will initially be available for the Atari 2600 platform, with plans for additional console systems to be announced in the near future."
The other joke was the announce of a new Hero Class released in Wrath of the Lich King : Bard.
From the website:
"The deeds of every great hero inspire countless songs of triumph, virtue, and epic adventure. But although a hero’s glory endures in song, the creators of those songs are seldom remembered. After ages spent singing of the heroic exploits of others, the bards of Azeroth are finally stepping into the spotlight on their own terms, proving once and for all that while just about anyone can pick up a sword or cast a spell, only a true hero can vanquish evil with the power of ROCK!"
"Armed with a trusty axe, killer riffs, and a ton of attitude, the guitar-wielding bard is the second hero class to be introduced in the upcoming Wrath of the Lich King expansion for World of Warcraft. The bard excels both as a solo performer and as part of a solid group lineup, able to front in a number of roles as varied as his musical repertoire. The bard’s extensive Metal skill line grants the potent transformational ability "I Am Murloc," as well as direct damage effects like "Epic Solo" that will rock foes into oblivion while powerful Indie debuffs such as "Tape Jam" and "Shoegazer" keep them in check. If things heat up, the bard’s Punk tree can support the party with a wide range of abilities, such as "Nonconformity," which dispels fear, mind control, and similar effects, or "Mosh Pit," which briefly boosts the group’s movement speed while its members stay within range."
"To fuel his or her powers, the bard uses a brand-new resource system called "groove." Selecting an ability launches the Fret Bar, which will display a number of riffs the player needs to activate using a new guitar-based keyboard peripheral that will ship with Wrath of the Lich King (a special Frostmourne-themed axe will be sold separately). The better the player’s accuracy and timing, the more powerful the resulting ability becomes. The riffs also become more difficult as the bard’s abilities progress, ensuring that the bard gameplay experience remains fast-paced and skill-oriented. Executing abilities also builds up groove, which further fuels the bard’s epic rock powers. Some abilities such as "Epic Solo" require a certain amount of groove to be unleashed, and the more groove, the more powerful the effect.
The time has come for the bards to claim glory for themselves. No longer will they remain shrouded in obscurity while less-talented adventurers are hailed by the masses."
They use weapons that deal "Rock Damage".
Funny. I had to think a bit to discover they were joking.
