Database Summary
Stands for "Sword Art Online." In this game, all players start on Floor 1 of an enormous floating castle called "Aincrad" and attempt to make their way to the top point on Floor 100, all the while exploring dungeons and fighting monsters. Players can choose to develop numerous skills, including combat, blacksmithing, cooking, and even low-key activities like needlework, enabling them to lead fully realized alternative lives within its world. The game was all set to become a breakout hit upon its release, but almost as soon as it official began service, the first 10,000 players found themselves unable to log out, learning instead that dying in SAO would lead to their actual death in real life. The only way to escape was for someone to reach Floor 100 and beat the game.
