In the year 2044, the world has been gripped by an energy crisis from the depletion of fossil fuels and the consequences of global warming, and overpopulation, causing widespread social problems and economic stagnation. To escape the decline their world is facing, people turn to the OASIS,[a] a virtual reality simulator accessible by players using visors and haptic technology such as gloves. It functions both as an MMORPG and as a virtual society, with its currency being the most stable in the real world. It was created by James Halliday who, when he died, had announced in his will to the public that he had left an Easter egg inside OASIS, and the first person to find it would inherit his entire fortune and the corporation. The story follows the adventures of Wade Watts, starting about five years after the announcement, when he discovers one of the three keys pointing to the treasure.
