Sword Art Online

Sword Art Online Dungeons and Dragons is based off of the novel written by Reki Kawahara.

The players enter a world in which they have never seen before when they begin playing the game Sword Art Online. It's the first game of it's kind, where players use full dive technology to enter the virtual world of Aincrad. The players are fully immersed in the virtual reality game, they experience all the pleasures and fears in the game as they do in their real life, but it seems so far away.

Aincrad consists of 20 different floors (as opposed to 100 in the novel/anime) due to restrictions on how many floors the players can reach before going epic. The beauty of Aincrad is that players will always have a goal to meet, beating the boss on floor 20, however they are able to take their time doing so. At the end of each floor there is a "Floor Boss" which must be defeated to pass onto the next floor.

However, in Aincrad there are no retries, no second chances, no extra lives. It's a kill or be killed world, which may be enough to drive even the most competent players to madness.
