Dual Family was one of my first adult VNs here on F95 and I have a soft spot for it, which is why I am so tired and annoyed of how Gumdrop wasted great potential for greed. When DF came out, it had really potential and still has some of this potential! But for this, gumdrop should make larger and finally sexier updates to DF1. Take the Father-Daughter path, in the new update, there is a scene where the two are lying on the bed and considering the story so far and how extremly close the MC and his daughter are, you can only say "for fuck´s sake, at least french each other finally! It is what both want to happen."
I still have a tiny little hope that maybe, just maybe DF will get a good ending one day, but that is simply optimism! I have seen and know enough of the history of this game to know what happened so far and I am more in the thread for all the comments.
