Anyone here who have seen SAO, have also watched Accel World?
I recommend that you watch SAO first, then Accel World.
This is why...
I don't know if anyone have notice but this two are somehow related. SAO is the first to employ full-dive virtual reality. What enabled it was the Nerve Gear. Approx. 20 years later, Accel World came to being and utilising a Neuro Linker instead. In Accel World, it was hinted that the Nerve Gear was the predeccesor of the Neuro Linker. This implies that the two stories are "on the same page". Will the story, especially for Accel World, reveal how it is related to SAO? This is one of the things I'm curious about. Obviously, I'm also wondering if Kirito and Asuna is still alive in the Accel World timeline.
I did some searching... I assume this is part of the summary for the novel ( this is from SAO wiki ).
Kirito is later recruited to assist in the development of a state-of-the-art game, UnderWorld (UW), which has an interface that is far more realistic and complex than the previous games he had played. In UW, the flow of time proceeds thousands of times faster than in the real world. However, he ends up falling into a trap set by one of the murderers from GGO and wakes up inside the game, unable to log out, with his real self left in a comatose state. As he starts to question if he is the real Kirito or an artificial intelligence modeled after him, Asuna, Suguha and Sinon also log themselves into UW in an attempt to help him.

Now about my tots on the anime 
At first I tot it would be another run of the mill fighting genre anime. I was proven wrong. It is has quite a deep story and a nice one at that. The hero and heroine are both strong characters, in that they can fight their own battles. I don't like it when one character becomes over dependent on the another.
The other part of the anime I like is what I posted above, about the possibility of a link to SAO. Hey what are the odds that Kuroyukihime is the daughter of Kirito and Asuna The Accel World story takes place in 2046, 24 years after the SAO ( 2022 ) incident which puts Kuroyukihimes at about the right age to be their daughter. On her forged ID, Kuroyukihime was born on September 30, 2032. Kirito and Asuna escaped SAO/ALO in 2024. Those events are just 8 years apart. Kirito and Asuna would have gotten married around that time. We also do not know Kuroyukihime's real name. This was confirmed by Niko a.k.a Scarlet Rain when they first met. They made self introduction by showing their "cyber" ID and Niko pointed out Kuroyukihime's ID was false. Furthermore, Takuma pointed out that the "cyber" IDs cannot be forged, but clearly Kuroyukihime's was. So who does Kuroyukihime know who can forge this ID. Must be someone who have strong connections in the virtual world.
By the way, there was a hint to Kuruyukihime's name. Sky Raker called Kuroyukihime "Sa-chan".
2nd ED Unite by Misawa Sachika, also the voice behind Kuroyukihime.
i remember reading somewhere that Kuroyukihime's real name was Yuki though so Sa-Chan might be related to her last name, or at least that's my guess. she's still my favorite character from both series though, even more than Asuna
