That's a good score, well done.
Did you enjoy it, though?
well, it just felt kinda pointless, like there is no significance in marrying one branch over the others or any reason to choose one family over another. also the ui is unintuitive since you drag your tree and the marriagable people from the familes, you cant zoom out, i had a very wide family and it was hard to keep up. i had so many descendants i ran out of people to marry into my family and i thought that since i married too much the other families sort of dried up in terms of marriable people. also everyone dieing is sad.
It's a late reply, but I want to make it anyway. The UI is indeed a bit unintuitive and we want to improve it in the future. You can actually zoom out, using the mouse wheel (or pinching on mobile devices).
It does matter which other houses you marry from since they have very different genetics which can have an effect on your family's offspring. But yes, it still misses a decent long-term goal.
