Is not me sayng it is the market, I wouldn't say "NTR fatigue", but more as stale genre with nothing new, you can tell just check how many doujinshi about incest/ntr are been released every week, many authors are seeing the necessity to try something new.Are we in the "NTR fatigue" era of NTR stories now? Like with superhero movies? Can we expect more deconstruction of NTR tropes now? LOL!
I been feeling a lot less sympathetic towards Kirito lately. Maybe it is because I am making him to do choices that get him action from other girls. Maybe it is because he and Asuna are just not spending anytime together. But that is the direct result of EVERYONE forcing them apart so it is not his fault. I don't know if Kirito's unintentional popular kids looking down at the unpopular kids (Inoda) attitude was meant to make us feel like he is should be cucked. But it just doesn't make me like this Kirito. This is a fanfiction after all. Even if the characters doesn't act like their canon selves it is alright. It is not like anything that happens in this story will make us change our opinions about the canon characters, right?
The problem with Kirito even in the canon SAO is the fact he is a OP poorly written caracter thats why he is not liked.
Here like you said is a parody/fan ficition with a lot of potential and very good ideas by Fujino, but not much different of many others ntr based games, You awake up, go into the map, do somenthing, you see somenthing happening and can't do nothing about it, log into the game maybe something happen or not them you endup at the memory room, rinse and repeat.
Instead why not change the POV or let the player cockblock the bull that would be funny.
