Played two games, both on Soyuz difficulty. I usually randomize all settings besides speed and size (standard/standard), but I wanted to see the new biomes.
Game One- ARC
Land on a peninsula with a bunch of bugs to the north -- hey, I'll just go into the ocean! Because it's the expansion and I can do that!
Clearly, ocean cities are the solution to the future of humanity, because I never needed to go to war with anyone to get the resources I need. My last CiV game was Ethiopia/Cultural victory, so I relished the fact that CivBE actually allows wide play by building a whole TEN cities (! TEN ! That's as many cities, as I have fingers on my hands!)
I had a lot of fun doing silly things driving my ocean cities around the map -- I had a city "filling in" tiles for other ocean cities that were already in good locations but needed more tiles. (Yeah, buying tiles would've been more efficient, but what's the fun in that?)
I enjoyed shopping for deals. I think it helps a lot that not all of the deals are guaranteed to appear in every game. ("It'd be nice if I could get a deal to help my cultural output...nope, no one took anything that helps with that!") I ended up cooperating with almost everyone, but didn't ally with anyone.
The AI seemed awfully amicable -- the tweets were full of attaboys and likes about how awesome I was doing. I thought about doing a war to mess around with new units, but the other factions were so fawning in their admiration, I couldn't bring myself to dow all my fangirls. Besides, if I needed more resources, I could just build more cities, because there was plenty of room.
Perhaps, in this possible future, Suzanne Fielding's incredible managerial ability, charisma, and omnipresent network of spies led to a time of cooperation on a new world, where all the factions cooperated and united behind her plan to bring the enlightened supremacy way of life back to the home planet. (Except Barre, poor guy never makes it in any of my games.)
I'll admit it was kind of fun to do things like establish orbital coverage over almost the whole world so I could be ready with Phasal Transporter on the off chance someone did something stupid like build a Mindflower. (ARC: They see all!)
Emancipation victory by turn 260-ish or so.
I was kinda disappointed at the end of this, and getting ready to cave in to the forum-fueled sadface train.
Game Two
This was actually much more interesting, and more fun game. Since I enjoyed the ocean cities I decided to play NSA. I had a slower start this game. I had a big inland sea to grow into, with my capital on the only entrance, I felt pretty safe. I don't want aliens wrecking my fragile sea colonies, so I farm them for science/culture. ("We're whalers on the moon, we carry a harpoon...") I try Might because health is so easy to come by, I don't feel quite as locked into Prosperity early game.
Kozlov is close to me, and he's actually pretty aggressive, and he also doesn't like that my growth rate is low. He has no navy (and one coastal city), so he can't really do anything to me, but since all his cities are inland and well-fortified it's not like I can do much to him. He is smart enough to keep his ground troops back for defense rather than embark them to be slaughtered.
I ally with Hutama. It seemed like a good idea to get the extra bonuses from the trade route deals, but I end up getting dragged into a bunch of wars. Plus, he decides to be a jerk and build the contact beacon, right around the same time I'm finally cracking Kozlov.
So I sneak a fleet into the back of his territory to try take it out, but he has a ton of patrol boats and hovertanks and he swarms it easily. So I have to go through the front way, and I use lots of orbital stuff like TacNet hubs because my cities can MOVE to give me coverage and I slowly dismantle his navy, cut through his outer sea colonies, and then trade a coastal base with him for a few turns before I get enough LEV Tanks up to establish a foothold.
Hutama gets Kavitha into the war, so I destroy Hutama's beacon and have to haul my fleet across the ocean to deal with her. Meanwhile I'm using an orbital laser to clear out the native wildlife in preparation for Earthling Settlers.
This is one of the more fun wars I've had in Civ, and I've always felt BE does war really well with different affinities having different bonuses. Hybrids offer an opportunity to mix and match. It's also an interesting choice, because if you shoot for a hybrid you unlock certain high level upgrades like infantry very early, at the cost of delaying upgrades that need a lot of a single affinity (like aircraft, and the victory condition.) And they look great! I love my immaculately crafted, porcelain navy of Purity/Supremacy.
As others have remarked, it is quite strange that they continue to send their positive messages even while you're at war. "You have sacked my capital, razed my cities, and destroyed my chance at victory...but I cannot help but admire your internal trade routes! Perhaps if I had internal trade routes such as these, we would not be losing this horrible war right now!"
Duncan's purity appearance looks pretty cool, befitting a pirate king of a frozen alien world. (I'm a little horrified that I ended up having to exterminate three major factions, and all I really wanted to do was mess around with a bunch of floating cities, but such is civ.)
Promised Land victory by turn 280 or so. (Fun fact: Earthling Settlers can settle on Coast now. Also, I could move my cities to make room for them.)
For me the biggest gamebreaker is the peace deal thing. Why do I have to wait for the AI to offer me White Peace? Why do I have to demand a bunch of crappy cities I don't really want because my warscore is high? There's some other stuff that needs tweaking, but this most impacted my fun.
TLDR: the game is still flawed-but-fun, in need of some polish.
Further: Soundtrack continues to deliver, making me feel like planting a farm is FORGING HUMANITY'S FUTURE.
Further x 2: Is it just me or something with my settings, or is the minimap really hard to read?
