[Kaioshin Sama]

Here's an interesting comparison between the two series, let's just take a quick look at the naming conventions of some of the major characters across the two works:

Yui(SAO)
Yulier
Asuna Yuuki(SAO)
Yuuki Konno(SAO)
Kuroyukihime (AW)
Haruyuki Arita (AW)
Sugou Nobuyuki(SAO)
Kirigaya Suguha, (SAO)
Kirigaya Kazuto (SAO)
Akihiko Kayaba
Sachi (SAO)
"Sa-Chan" (AW)
Sasha (SAO)
Fuuko Kurasaki (AW)
Chiyuri Kurashima (AW)
Yuniko Kuzuki (AW)

Yoshiyuki Tomino would be proud of how totally not at all a similar sounding all those names are.
