Largely because SAO took over its spot, I suspect.It even took over the video-game niche; 'Sword Art Online Hollow Realization' feels like a different company made a new version of the .hack games — a bunch of improvements, and some changes that are a bit strange.Though if the 'settings' were reversed, there's certainly one problem of anime-SAO that wouldn't have happened; Using mixed keywords instead of levels in a tower would mean a lot more 'training ground' for newbies, so no 'beater' issues at the start.
