For a full on game I have a plan to manage this sort of thing, but there will be somewhat pre-determined stories since a computer couldn't exactly write a compelling narrative. Those stories might have certain dialogue added depending on player choices to give the illusion that it's totally dynamic.
Bad Example: "Remember when we were "insert place here" and we had that conversation about "insert thing here?" It was "insert weather" that day, I felt "insert emotion here."
Meanwhile, the main story is somewhat on branching rails Telltale style with the side content being actual dynamic social simulations.
Whoa, you donated again? Thanks again!
If I decide to do crowdfunding I'll make sure you get the appropriate reward tiers with no extra contribution necessary.
I understand and I like your thinking; I don't know how to draw support to you yet so I'll just keep donating.......#Donate_to_this_game
I've already got way more support then I was expecting. This was mainly just a pitch game to get people on board for a bigger game after all.
