Sword Art Online

[MFauli]

i guess in the end it is of not much use to give too much thought to this series. i mean ... this is a world where the matrix is real. people can log in to perfect vr-games and do whatever they want. there are so many socio-economic factors that SHOULD be at play here, that it is absolutely ridiculous how the real world in sao seems to be the same as ours.

EDIT:

As for ep 18: I dont get it. So does his sister know she´s playing together with her brother ... or not? When she pauses the game, she knocked on Kirito´s room door, fully expecting him to answer. After leaving him dinner on the kitchen table, she returned to the game and called the Spriggan "Kirito".
So ... what am I missing here?
