The flipside of the whole "The artist who endeavors to enforce a lesson, becomes a preacher; and the artist who tries by hint and suggestion to enforce the immoral, becomes a pander." is the fact that when there is no "lesson", you are just accepting and reinforcing the status quo. One example is Dragon Age: Inquisition, in which the actions of the main character are extremely questionable, but unchangeable (particularly the romancing of character who treat you as "my Lord" and the whole "Freemen of the Dales" thing).
Most games, ultimately, have moral content, whether or not it is acknowledged. It is fine to focus on mechanics and just accept the ethical status quo, but the opposite is also valuable, if done tactfully.
Fallout (the first, maybe second) is one of my favourite games dealing with choice and consequence, beyond Ultima. Also, the game Open Sorcery: Sea++ is extremely good at it. Sometimes the "good" action simply requires a bit more work to find.
Anyway. The game is looking really good, looking forward to it.
