World of Warcraft: Warlords of Draenor contains what can only be a tribute to the late, great Robin Williams.
WoW expansion Warlords of Draenor is currently in closed beta testing, and fans have uncovered the promsied Robin WIlliams tribute.
The tribute is an NPC named Robin. To see him, travel to an island off the Talador coast and rub the Ever-Burning Lamp.
That the genie is a tribute to Williams seems certain; apart form the name, the NPC exclaims things like "infinite cosmic power" and "itty bitty living space" - lines from the Genie in Aladdin, a role Williams largely ad libbed.
Keep exploring the island and you'll find a broken egg - a reference to Mork, Williams's character in tv show Mork and Mindy.
Wowhead has pictures of the tributes, as well as a couple more datamined Robin NPCs which may also be tributes.
A huge World of Warcraft fan, Robin Williams passed away last month. He will be sorely missed.
