For me this series is considered a alternative reality with the same ending as first GGS, but it's focus is on Wu Bai/DT, Han Shang Yan's cousin and his lovestory to Ai Qing/Appledog.

It's alternative reality for some reasons:
*The season one game competition is all about hackers game while season 2 is all about robotic game
*In some episodes we will see some scenes which doesn't exist in season 1..The storyline happens before and during the events of season 1,with some different scenes but with the same ending;to be exact an extended ending on what happen to season 1, like double wedding celebration of main characters of season 1 and 2..
*The female lead of season 1 is more like a noona personality, while season 2 is more like acting the same age as Wubai
