The entire discussion of speed of progression and content is moot. When people started to make fan images, fan comics and fan games, the Main Game failed. Now the dev is boxed in, into that part of the market that isn't supplied.
You like mother humiliation, play Aiden's Revenge
You like Incest, Orgies, Dilf and Family Fun, read ST9-Pol comics
You like Mom Son, play Motel-ASAB
You like Corruption and Slut training, skip the AWAM-verse and play Project Miriam.
Brother-Sister and honest Mom-Son or any Sister-Sister romance is not yet supplied by third parties.
If I make, Stellar Conflict, Space Skirmish and Solar Battle, plus the Znyder Wars Series, before the mouse makes the next Star Wars, what else are they supposed to do other than more Super Hero movies?
TL DR;
Be happy the game gets updates with content you haven't seen anywhere else before, the options grow thin.
