"In the year 2044, the world is gripped by an energy crisis causing widespread social problems and economic stagnation. The primary escape for most people is the OASIS, a virtual universe, accessed with a visor and haptic gloves. It functions both as an MMORPG and as a virtual society, with its currency being the most stable currency in the world. It was created by James Halliday, whose will left a series of clues towards an Easter Egg within the OASIS that would grant whoever found it both his fortune and control of the OASIS itself. This has led to an intense interest in all aspects of 80s pop culture, which Halliday made clear would be essential to finding his egg.",
