Just going based off of Chaos;Head, if the issue you have is fanservice (my issues with S;G were mainly with that and), there will be some of that and it will probably be based on your choices."but he's a guy!!!"
But I feel like the large jump in quality from C;H to S;G, and then the vague improvement to S;G 0, means that Child will probably be at least slightly better about that stuff (since it came out before 0)?
Yeah, the fanservice and how some characters were treated was really offputting. Most endings in S;G were bad too because you could tell how shoehorned some stuff felt.
Im already expecting some fanservice, just hoping for better endings and that the childhood friend isnt Mayuri 2.
