I hear ya, but any game that has pregnancy always means more work for the one or two devs that are making the game. Very few of these games has a whole team behind it. 3D games are the hardest to do active preganancy mechanics as you'll have to do double or triple the renders that you'd normally have to do. 2D games tend to have it more often casue creating a 2D image is almost always way less work intensive. In a perfect world, I agree that everygame where pregnancy was an option that it would be available whenever. However, that's just not reality at the moment.
