I really really like the game. Especially that your choices actually have impact on the story is a fresh breath of air.
However, I also have to agree with some other comments. The ending is a bit...abrupt, and if you have pregnancy turned on and the PC never actually knows about any pregnancies, then that's a bit disappointing.
I'd second the idea of playing at least another few turns, maybe adding two locations or something that the player travels through.
I'll be following the progress on Eternum though :)
