* Most of the time, Find a Spouse doesn't work at all. As far as I can work out, it locks up after the first action you take on the Family screen, regardless of what that action is.
* But that's not an impediment to reproduction, because you can Have Child With Spouse even if you're single.
* Spouses are non-entities. This sort of negates the point of having them at all; if spouses lack distinctive personalities that can influence the game, then they're deadweight both for gameplay and for story. (I'm assuming that this is planned for later.)
