I have been away on another country without my laptop for a few days and just came back, sadly as if my luck was cursed every time I tried accessing this site or Ci-En from my phone it seemed like every wifi network from the airport's to the hotel's I was staying at were 'privated' enough they blocked them because of 'explicit content', lol. Just caught up and see there's been a lot of talk, probably because Fujino hasn't updated yet, but well, 7 days left for September to end so not much more to wait for at this point.
Also, I wanna say I half-agree with this argument, while knowing the source material can help 'enhance' the experience somewhat, Fujino makes the game's setting distinct/unique enough that you can play them without knowing it at all and still enjoy them, hell, in some ways you may enjoy it MORE actually, as I mentioned ages ago as someone that actually likes SAO and knows the source material quite well I have pointed out countless of things where Fujino clearly either didn't remember/care to remember at all to write in the plot which create massive plot-holes you only notice if you know the series, all of which only exists to enhance the 'NTR' feeling of the game (Like Suguha's whole Canon plot somehow not having happened despite him implying the Fairy Dance Arc happening with that 'nightmare' Kirito had of Oberon fucking Asuna, which besides not making any sense only served for the purpose to allow Suguha to get 'NTR'd and for Kirito to not know Leafa so she can get further "NTR"d more in the second part in VR too). So I would actually say that having minor or not real knowledge of SAO (Or just hating the characters a lot I guess XD) helps enjoy the game way more.
