On the one hand (no disrespect to our fellow cfc's) I wonder how many people would appreciate the jauntedness of a cartoonish/cute look in a dystopian game. I think it would go over a lot of people's heads and, as I said, make it all the more easier for them to kill millions of people rather than think twice.
That's good. It makes you think that you are playing a game, like you actually are. Eventually someone tells you that you are actually killing millions of digital people ("OMG, it's so deep!"). It can be social commentary on the nature of warfare in the information age, with drone bombardment, combat through cameras, and nuclear strategic maps. Your brand new genocide, now with extra monsters.
It's like how in original SMAC, they had nerve stapling, but never described what it actually was (I assume it's something like an amplified lobotomy); how you could overuse it if you avoided the wrath of the Planetary Council without actually realizing that you are committing atrocities. It was also your decision to be made: the game never told you what to do, which is the advantage of video games as a medium and possibly as a form of art.
I feel that DEFCON did this to a degree, but it was too simple and too obvious being based on the Cold War. With this game, you have a variety of choices and the mood could change instead of simply being depressing. Like when you are researching early tech the music is upbeat but the worse decisions you make the more moody it becomes. You could even have a colour filter like EU4 has with the seasons to amplify this, but that might be too much. Mismatching music and graphics could already make the game unsettling.

The only problem is that it has to be a game, so it has to force you to do some things in order for you to play it. Being forced to do things was a complaint I heard lodged against Spec Ops: The Line, which was a shooter which tried to deliver an Apocalypse Now style storyline. It made it more into a movie than a video game, you can't just say you can shut the game off to excuse it forcing you to do things a certain way since in real life you don't constantly have a single path through every controversial decision and you can't just shut reality off (this is debatable, technically you can do so for yourself but reality still goes on, the game doesn't give you an ending if you turn it off). I hope the CivBE "narrative"/tutorial doesn't tell you some stupid lie like nerve stapling (or whatever it's called in BE) is the only way to solve riots. You could then say "Oh I was just following what the game told me to do" but the whole point of it is that YOU are in charge, YOU are the faction leader, YOU did this.
With SMAC the one thing that felt forced made sense: technological progress. Even if you disagreed with what your scientists were doing (given in the little blurbs that only appeared when you discovered a new tech for whatever reason) you had to keep up with your competitors, and this is true in reality as well. Most other things were left up to you. It would be nice if CivBE doesn't railroad players into one of the three affinities, since they aren't exactly the only ways of progression. Alpha Centauri's tech categories of Explore, Discover, Build, and Conquer were good in the they were generic, and each had its advantages and you didn't have to switch social policies upon discovery of a technology which enabled them, but in the end if you wanted to match wits with the other factions you needed research balance.
What's really nice about Beyond Earth is that it's really about us, about our generation and onward, and it could be a serious reflection of humanity in the 21st century. We can't just say, oh we can go warmongering because we're playing as Genghis Khan and this is the 12th century. We usually consider themselves, implicitly if not explicitly, better than that now; but are we really better than we were in the past? If done subtly, not pretentiously, BE could really be a great work; something to be studied, to be considered in discussion. A unique creative experience, not just something to be played with.
EDIT: Should I email this to them?
