##### Cross-expansion integration

We’ve been following feedback across the community (Reddit, Steam comments, Twitch, YouTube, and our insightful testers on Discord) to try to make sure all the details are covered. It’s a very complex game at this point, so there are quite a few details - having feedback from tens of thousands of people is frankly invaluable from a design perspective.

One theme that’s come up is the desire for integration between expansion packs. Originally, I was a bit hesitant to put this in because I worried it would feel like locking one expansion’s content behind another expansion. However feedback seems to indicate that people want it, and narrative-wise, it would make a ton of sense if the ideoligions from the Ideology expansion had beliefs about xenohumans, sanguophages, children, and so on. So I decided to work on this.

I’ve found over the years that the wrong way to design Ideology precepts is to just think of something that seems fictionally reasonable and implement it blindly. You end up with mechanics that “make sense” but aren’t actually storyful or fun. Instead, we decided to take a “goal experience” approach to the design: We wrote down a list of the specific play paths and role-play stories that players might want to explore, and which would also be fun. Then we created precepts that specifically open up those play paths:

**Belief issue - Bloodfeeders:** The vampire lord with human worshipers is a classic idea. So are the vampire hunters. This precept changes peoples’ attitudes towards people with the _bloodfeeder_ gene (which in Biotech means only sanguophages, though you can of course create your own bloodfeeder xenotypes).

Those who _revere_ bloodfeeders will want them around, love them, and be fine with being fed upon. Those who _revile_ bloodfeeders will hate having them around, despise them, love killing them, refuse to become them, and hate themselves if they are one. Bring on Dracula’s thralls.

**Belief issue - Child labor:** We always had the idea of players being able to choose to invest more or less in children - to decide between using them as workers or fighters, or trying to strengthen their development with a rich and free childhood. Now ideoligions can have opinions on how this ought to be done.

Those who _encourage_ child labor will have children who work faster and not like assigning children to recreation. Those who _disapprove_ of child labor will have children who learn faster, but adults won’t be happy if childr
