Alfheim Online; introduced in the first
season of SAO. SAO is both the
title of the anime and the name of a VR
game in the anime, just like ALO.
Otaku 1: I prefer ALO over SAO, because it has magic!
Otaku 2: That it doesn't have magic makes SAO more likeable in my taste.
Otaku 1: Dudette, you die in real
life if you die in SAO.
Otaku 2: ... Don't mention that.
