I don't like it when in some games you're deliberately sabotaged by the developer to lose.
This usually happens when the conditions are annoying to fulfill, causing you to give up.
In this game, the story is linear, and you only control the scope of the resulting fallout at the end of the game.
The best strategy to get through these types of games is either having a "revenge outlook" or simply not caring.
This game feels more like saying, "you know what, you all are so dumb that you deserve it."
The problem with this is that you are approaching a NTR game, this one in particular, with the incorrect mindset.
I understand your grievances with games stacking the situation in order for the MC to get the short end of the stick time and time again in Netorare games, I have similar problems with many games myself.
The issue at hand is that Sword Art Online Conceal Breath is not a game about a main character trying to win over a heroine or trying to repair his relationship with the female lead. The core of the game is following up Kirito's misfortune as the world around him steal everything he has.
The game is in fact nothing more than a medium for Fujino to tell a story he wishes to share and to showcase different erotic scenes to us as an audience.
You can very easily tell this by the fact that SAO has practically no gaming elements, Kirito is immortal and all combat mechanics boil down to pressing attack until Kirito wins the battle, meanwhile you just walk from place to place witnessing the lewdness around you.
You could compare this type of hentai game with the many "walking simulators" that are very popular mainstream games, where the player doesn't impact the story, as they simple experience it throughout their gameplay.
And while I do have a problem with the entire world being stacked against Kirito from a narrative perspective, it's not the same as a game that forces the player to lose. Because it was never about winning or losing in the first place.
TLDR: This is not really a game, it's more of a barely interactive NTR Doujin from the cuck's perspective.
