I don't know anything about memes or whatever (unfortunately people I know actually LIKE it) but having twice tried to watch it, Sword Art Online kind of feels like trash to me. It was just so boring, the characters were extremely one dimensional, and nothing new or interesting really happened.
Also, if you want inspiration about digital worlds just play some video games and think about what it'd actually be like to be in them. Do a first-hand experience, not a second-hand knock off.
This theme has been done to death so you really want to come at it from a fresh perspective, not regurgitated anime.
Edit: Oh, and watch that one movie with Ryan Reynolds being a video game character because it's amazing.
