Funny thing, that actually is the SECOND chapter of that particular Fujino storyline, the first game before that one is Scathatch chapter which shows you how the FGO MC got there and in Shirou's house to begin with.
Also, no, sadly Fujino stopped doing that one and did SAO instead, but he did say a while back he wanted to go back and finish his Fate games after being done with SAO.
As someone who only stayed reading SAO BECAUSE of the FD arc (As it was Suguha's beautiful character arc and feelings what made me keep going despite how shafted she got AND kept going after that...has anyone realized she's not only the single heroine that had to SHARE her own arc's focus with Asuna, but also wasn't even present for the climax of said arc XD?), I can't say I agree with that, and also think people really overfocus on one aspect and completely overlooks everything else, especially because Sugu (As much as someone who only consumes this NTR game as SAO content can forget

) is specifically written AGAINST the usual stupid cliche 'Incest' Tropes most harem series used, she legit suffers from her feelings and does her best to get over them and even comfort her Onii-chan when he's completely broken so he can keep going after the one he loves despite how much is breaking her own heart to do so, because for her his happiness was more important than her own...and her only reward is getting her heart broken TWICE, and yet she still chooses to keep supporting his happiness over her own XP
As for Kirito being 'Too OP and the girls fall for him', LMAO, this has always been the shittiest excuse ever for hate against his characters when literally DOZENS of other similar ones that were a million times worse in that aspect came out in the years after SAO's first season yet it was only Kirito and SAO who even remotely stayed in the spotlight of the 'haters' (Who are a vocal minority anyway), it was always SAO being so popular what triggered most. Especially when LMAO, Kirito literally is suffering brutal emotional blows and trauma every single arc almost like his author got off on it, especially in Alicization XD
