Elder Tale

Elder Tale is a massively multiplayer online role-playing game and it is the main setting of Log Horizon. The online game takes place in a post-apocalyptic world.

Background
By its eleventh expansion pack, Elder Tale has become a global success, having a following of millions of players. However during the release of its twelfth expansion pack Novasphere Pioneers, 30, 000 Japanese players and several hundred thousand players worldwide who were all logged on at the time of the update ended up trapped in the game.

Now since then, every guild in Elder Tale began a widespread campaign to recruit as many players as they can in order to survive the new world ahead them.

System
The game operates like most MMORPGs with a level system and eventual skill mastery of character classes and sub-classes.

Virtual Reality Experience
Though it's currently unknown how players play in Elder Tale though it's mentioned by Naotsugu that they play through PC like all other online games. But since the entrapment of the game, players seems to experience being in it literally.

Environment
The world of Elder Tale is based on Japan's Half GAIA Project (ハーフガイア・プロジェクト), a half-scale model of planet Earth. The differences between the GAIA Project and the world of Elder Tale is the post-appocolyptic setting.
