Here goes a little review by me after playing the demo.
Early positive effects:
If you're an old player you'll notice soon that some very basic, major changes have happened. Obviously the terrain is hexagonical, stacking of more than 2 combat units is not possible and there are things like the city states which make the game all that more interesting. Also the map's cool, you do no longer know if you're high up or far down, which makes it all more fun and exciting.
But those are as mentioned the more obvious features.
I began this game as a Persian (one of 3 civs in the demo) due to their early unique unit and increased effect of golden age. I wanted to try out as much as possible during the 100 test turns you get as a demo player.
The beginning of the negative ones, sliders, settlers and combat
The first thing I noticed was the lack of sliders.
No more sliders for research or happiness.
As the game progressed I would also learn that happiness works very differently than in the previous games. But more on that later.
Since I started at a place with little resources and alot of grassland/flood plains I attempted to go for a fast expansion and a strong military first instead of building a bunch of buildings. A scout and then a worker.
I sent out my warrior and later my scout to explore in different directions.
As you meet your city states you get 30 gold if you were the first one to meet t hem. After that there's not much to do. Either they send you on missions (very rarely, and they are bugged - I once killed all barbarian tribes on the map and it still wouldn't recognise I saved it from pestering barbarians) or you have to lick their ass. You lick that ass by giving them huge amounts of gold or free units. This boosts your influence with them.
Sadly this influence keeps falling if you do not continue to give them free stuff. Ofcourse you can also invade them. The computer seemed to like giving them free stuff and befriended them. I didn't care for it to much - a strategy that would later prove to be sound.
My first big huge disappointment came with the way settlers work.
They do not take population from the city anymore, instead they grind all growth to a halt. It doesn't matter if you are producing +10 or +1/0 food per turn, it all turns into 0 while you are producing a settler. Fucking bull I thought and produced my settler.
During this time I had killed a bunch of barbarians and goten some gold and thus financed my army. Production can no longer be hurried half way, instead you can pay for units as whole and these units are then created instantly. Again something that seems unrealistic and cheap. This way you can always keep 1000 gold if an enemy is attacking and buy defenses fast for any city.
A positive addition is
CITY DEFENSE. Cities aren't places without any will or spirit anymore. They can bombard units and depending on size and location they can defend themselves very well. City combat becomes like a real siege, it takes quite a few turns to capture one. Even with an overwhelming force.
EDIT: I changed my mind. For small cities it works. For big ones its absurd. The city doesn't lose population when attacked nor defense. So if a city starts with 9 pop as London did when I besieged it and 24 def it will keep those numbers indefinetly. I wasted an army of 6 UNIQUE spearmen, 3 cav-archers and 1 group of swordmen (most advanced unit anyone seemed to have) against a city with no defenders and lost. (Pushed like crazy so to make it before the 100th turn). Very badly balanced. Seems like they wanted to lower the ESB rating by not allowing civilian death losses or something stupid.
Combat movement and combat overall is quite bad though.
Many units can't move and attack which means that ranged units get screwed over quite bad. My chariots became my cannons because I never could explore with them, move near a unit and then fire and such. They always had to be behind infantry and act like long range bombards. Completely moronic. Completely loses its purpouse. I wonder how the mongolian horse archers would have felt playing civilization...V
EDIT: Seems you can attack as long as you have MP left. But if you run out and end up standing besides an enemy you can't do anything. Not to bad though, don't mind it as much as when I thought I never could attack at end turn.

AI, concepts and overall analysis
The AI is stupid. No doubt. I was playing on emperor level wich in the old games would have meant a far bigger empire for the AI than my. And more advanced units. Instead it seemed to be spending all its extra cash on licking city state ass (to the point where one of them attacked me - not that I cared). It also had 1 city less than me when I assulted it, despite starting at a better location. It also spared one of my units for some stupid reason when it had the chance to destroy it, instead attacking a fully healed one. Crazy.
More on happiness and government rule;
Happiness is now nationwide, no longer can cities revolt and no longer can one city be happy and an other sad. Angry people mean that growth is slower and not much more than that. Without the ability to change sliders there's not much a man can do. This is the one thing I'm not one hundred percent sure on this but almost. At the very least the main focus is on nationwide unhappiness.
EDIT: Game almost finished now and I'm not making any improvements for happiness to test this out. Still no revolt, I assume there is none.
There are no different governments, there is no anarchy. There are policies you buy with culture points. This idea isn't that bad, though late game must become very rigid. As you can not have authoritarianism and liberty at the same time. Which means if you want to change to authoritarianism you have to buy all those policies from start. I guess it is good in the way that changing a political system shouldn't be easy. Yet is it realistic? Look at Lenins revolution or Hitlers grab of power...wen't pretty fast IMO.
One of the worst things that greatly limits the effect of pillaging is that you no longer need roads between your resources. If you simply have a pen around your horses, every city on the continent gets access to horses.
The Interface is not much better, it's slightly more confusing and the civilopedia is a mess. It's not alphabetic, it lacks pictures and finding something takes alot of time considering that the search engine requires an exact spelling of what ever they had in mind.
For example it won't find an article about city states if you write city state.
Nor are there the old links from Civ 3's civilopedia that for example led you from wheat -> grass land -> something else making browsing fun and the chance to learn something new greater.
Other things:
Overall - even if you ignore it is on Steam - this game is a big, big disappointment. The graphics are alright (I'm running on medium) and the sound isn't that bad. The starting video can not be canceled until half way through and that got annoying at the second start.
Sound in terms of effects is rubbish and unfulfilling though but is lifted up by some good voice-acting and other interesting things.
The tutorial at the start is great, it works like the old Civilopedia did. But once you click the most recent part of it down its gone for ever.
I'd like to be able to give this game a higher grade for being Civilization but I can't. It gets a
5/10 for still being a good game with a sound base. But most of the new things either don't add much or are hampering. And it's simply not that fun to play. Almost as if Civ 4 was the Spore beta and this is the final Spore product, worse than its own beta.
Thanks for reading
IF you have any questions or such I'll answer them to the best of my limited abilities. I've also got about 30 turns left on the demo. So if you want me to test soemthing ask that to.
