I really don't know what to do with this statement. I don't understand why you keep thinking that players only care about this because of the incest angle. Is the concept of a familial relation bond that alien to you? Maybe we like to immerse ourselves in a story and world that seems authentic. Not dive into a porn logic filled novel.
I like to know who the characters are and where they came from. Backstory and lore adds to the experience. We had that prior to the coming changes. Now the flow was disrupted
again. And I fear that he'll replace what we had with some moronic AVN trope. Imagine if his solution is to turn the Zane's into more of a clan instead of a family. How fucking retarded would that be?
AHA! I knew it! You are a believer in the Adoption Theory too! I got you now!
But seriously, the reason why I abandoned that theory is that Katie will most likely remain an LI. Blood related or not, if they're adopted, the inquisition may still view them as family. Which can cause problems. Ocean nuked his stories to make sure they'd be bulletproof and safe from the Inquisition in the future. I doubt he would risk it going the adoption route.
