Age of Conan is a massively multiplayer online roleplaying game (MMORPG) that takes place in the world of Conan The Barbarian.

In "The Barbarian Sublimation" (S2E3), Penny becomes addicted to the game and, as a result, she constantly harrasses Sheldon for advice and help in the game. Only making a date with Howard in-game finally gets her to quit.
