Hopefully someday we'll be able to pre-set the kind of kids we want from impregnating the prisoners on Gastigoth.
It's possible to miss the email from Arno Kramer asking if you want your children to be natural, safe-edits (taking the criminal tendances away), or custom (super) children. Since it defaults to natural if you fail to respond, I just think there should be an option there (especially if it's a repeat pregnancy) to set it to safe or custom edits on the future kids DNA.
I keep picking the customs, since the player character is after all also a custom edit... if it worked for ol' Victor Steele, it should be good enough for us too. But spending anytime with the Frostwyrm, rebuilding the race usually winds up with me missing the various emails, and it defaulting to natural instead of the custom I keep picking any other time.
