No you're not doing anything wrong.
There isn't any additional content that can be unlocked through that way.
Originally when I started the project I intended to do more with the original matrons, but then I sort of got lost in the system that drives the generation of daughters and the random encounters.
Had the great idea while in a lot of pain that it would nice to give people some sort of extra content while waiting for me to finish adding more content and specific daughters.
That didn't work out so well.
It ended up being a lot more work to implement the system, gather images, format images, edit images, and write the dialogue/scenes for the individual personalities.
I just didn't realize how much work such a system would take. *sigh*
Because I ended up getting incredibly busy with other projects, it took me 2 years to actually get the Generations update out.
As much as I would like to say I'd go back and finish expanding those characters, I have no plans to currently.
Just working towards adding the overall necessary story content to round out the game to bring it to a conclusion this year.
There are some extra bits of polish that I'd like to add, but don't want to make promises I can't keep.
