If you feel disappointed or think this is the worst update, then your feeling is totally legitimate and it transcends nationalities and cultures.
At this point I will skip the analytical process and just jump to the conclusion, because rational reasoning seems to be meaningless facing the content now presented in the game.
1. Fujino is exhausted, both his passion and innovative ideas:
I think you may get this feeling from how Fujino now treats the game. Fewer and fewer content, after long interval of update. If you look back to the last few updates, you may see that after two months development there is usually 1 or 1.5 day content in the game.
2. Fujino is rushing to finish this game:
I think we may all agree that Fujino is not a very talented writer. This game already contains a lot of plot holes, but as I commented before, they are sort of tolerable because I can see Fujino's hardwork to try to make the story logical.
But in the recent updates, such effort is replaced by the convenient tools dumped into Inoda's pocket: Memory change, brainwashing, powerful item from the quest with Yui, and even Yui herself. Fujino is turning all the things and characters as tools to help him reach the finishing line, not caring whether it makes sense or not.
3. Fujino is immersed in the game fantasy:
In fact, I am concerned about Fujino's psychological wellbeing. I can empathize that this game must mean a lot to Fujino, considering his condition of leaving China and all the familiar things around him, leaving alone in Japan with heavy workload.
In recent updates, I see the dangerous signs indicating that Fujino has inserted himself too much in the game world as he projects himself into Inoda. Let alone Asuna who is so obvious, does anyone have the experience of playing a NTR game where the bully fucks his own daughter? I have a feeling that this will happen because Yui is offering herself to Inoda (very obvious in their dialogues in the Chinese version), and she will be an important helper so there is no reason why Inoda will refuse (plus oyakodon sex scenes of Inoda-Asuna-Yui). Not sure how you feel, but this is disgusting if it happens, and I hope Fujino can realize and doesn't go there.
4. In his future game, Fujino should make it short or medium:
It is apparent that a long story is beyond Fujino's control. This includes a long and complex plot, multiple side characters, possible conflicts, conspiracies, and a big world context. Fujino should avoid these and just focus on a streamline simple story: the Antagonist ntrs of the MC's FMC. In this way, Fujino can spend more effort to create high-quality CGs, which is what he is good at. You can feel this difference by comparing SAO1 and SAO2.
