If we're setting aside the aliens, the tech web, the unit upgrading system, and the Virtues, then yeah. Nothing's changed. Totally worthy of a thorough lashing.
<.<
Aliens feel like glorified barbarians. Alien nests are barbarian camps. You could achieve the same feeling of the dangerous unknown by playing with "raging barbarians" on. Sure they can be passive most of the time if you leave well enough alone. But a harmless colonist or explorer happens upon one? Gone for no reason. The waterborne aliens are also just assholes with no behavior pattern other than "kill anything in my sight." Aliens don't feel like indigenous life. They'd be more engaging if it was like, certain aliens grazed on fungus, but I need to build a plantation on that fungus for my city. Or if there was some immediate benefit to letting them live other than not pissing off AI that like aliens. The alien variety is also incredibly lacking. You have siege worm, sea dragon and kraken, wolf beetle and raptor bug, manticore and other ranged thing, and then the drone. That's about it.
Virtues are consolidated social policies and the tech web, while allowing for more freedom of choice, feels like a step down from Civ V's tech tree in just how confusing and unintuitive it is. Trying to figure out what you already researched is a minor chore compounded by the fact that I have to do that every time I choose what to research. Wonders are indistinguishable from regular buildings other than the build cost. Very few of the wonders have anything worth pursuing either. Also no world wonders.
City states have been replaced with one tile stations that offer no resources and the trade benefits are minimal in later game, even at tier 3. You're better off trading internally for the mondo production boosts.
Orbital layer and affinities are about the only substantially new things I can point out. Even the orbital layer I've rarely had to use other than eradicating miasma and the occasional solar collector I get from expeditions.
I think my biggest issue with the game is that it feels like the devs were really scared of any one thing being too overpowered, so instead they made everything bland. It's been balanced to the point where nothing is special. None of the civs feel unique, which is quite an accomplishment considering there's only 8 of them. Not even the affinites feel like they make my civ particularly different.
It's been said, but the game lacks personality. Civ V feels like it was designed with a passion and reverence for history. It has an ornate, art deco UI that is still easy to read and understand. Civ BE should feel like it was designed with a reverence for space, science, and discovery. But instead it feels bland and soulless, opting for for a minimal looking UI that doesn't look inspired by anything. I like minimal, but this feels phoned in and ugly to boot. Teal, pink, blue, purple all combined with black seems to be this game's main color scheme. I don't think it works and it doesn't evoke sci-fi. What about white? Beyond Earth's box art with the astronaut in front of the window. It would have been better if they went for a look that was more in line with that image.
I was never looking for Beyond Earth to be a wildly different game from even vanilla Civ V. I was ready for "Fallout 3 to New Vegas" levels of change. I wasn't, however, prepared for how much is absent in Beyond Earth that makes Civ V such a better experience.
For new Civ players, unless you reeeaaaally won't play a Civ game unless there's a thin sci-fi veneer over it, I'd reccomend getting Civ V with the expansions over Beyond Earth. BE won't escape the identity of "reskinned Civ V" until the BE expansions come out.
I didn't mean to rant, but damn, between XCOM, Civ V, and their respective expansions, Firaxis was on a roll. So that just makes Beyond Earth more disappointing to me.
