Oba-san saga had no younger characters introduced in the game to begin with. This game does and they're fully drawn.
All that wall of text only for your argument to fall to pieces by few words.
Stay strong, buddy.
No shit Oba san Saga had no younger characters; IT IS LITERALLY CALLED OBA SAN SAGA. OBA SAN IS A WORD THAT IS USED FOR OLDER WOMEN. In other words, I am saying I did not read the title called "Oba San Saga" and think "Gee where are the younger women at?" IN GENERAL.
Obviously, the TITLE TELLS YOU what to expect. It does not matter if Mama Sans of Destiny has the daughters drawn in, it is not about them and is about the MILFS. If you have a problem, that is on you for playing a game literally telling you to just expect milfs. With Oba-san saga, just because there weren't any characters that were younger drawn in, doesn't mean anything. The point is that you are not supposed to even THINK about them because you are told ahead of time that the game is not going to be about younger females.
You are missing the point.
Literally your whole argument is based off of "Muhhhh THEY DREW IN THE LOLI CHARACTERS WAAA" like as if that is an actual point. The artist wanted to do something more and draw out other characters. That is not new for any hentai game to actually have art of characters who you can't bang. This artist decided to do so. The only one with an issue is YOU, the guy who played the game flat out saying, "Hey this is only going to about milfs" and thinking you were going to get non milfs
The most you were going to get is what we got, milfs and easter egg scenes involving characters that were in the last game because this creator literally always features his past characters in easter egg scenes. To expect a loli involved scene and complaining is dumb. You would have had a right to complain if in the story we got full art for milfs that never had sex scenes. In either Oba san Saga or Silly Girls Quest, that actually happened. I think it was Oba San Saga though where there are fully drawn in CGs of milfs that do not have any scenes in the game. They are just there to be easter eggs of the artist's past work but is pretty disappointing that they have no scenes in a game literally about Oba-sans. THAT would have been a situation where it made sense to complain.
Also, the game literally has no Loli or sister tag. Why the fuck did it not pop in your head that you would not get a daughter scene when you saw them? "Well why didn't he just make them into milfs" because he just didn't want to. End of story
