Can't wait to pirate it in 2032 after waiting for it come out of early access since 2027!
A universal complaint I have that applies to all modern games is the time between announcement and release, and I don't expect this to differ on that front.
The trailer was
gross. Which I'm going to say was the point, and I think it emphasises it by turning initially non-disgusting scenes disgusting once the celebration turns sinister. I had to come to this thread after seeing people say the trailer was created specifically to laud the scenes taking place within which I find baffling.
You got the usual medieval merriment with the occasional debauchery, right? It's like a fair, parents and kids, dancing, singing, and so on. The first instance of vomiting in the pig pen was meant to be comedic. The orc-guy has had too much to drink, but after spewing he raises his tankard, smiles, is smacked encouragingly on the back and someone cheers. I think this initial presentation of events
before the turn is giving people a mismatched perception of the trailer's intent. It's
because this wouldn't be too out of place and it initially doesn't seem all that bad that it helps amplify the actual fucked up nature of what's happening when the complete picture is slowly revealed.
Compare this guy's face during the day prior to the reveal vs when we're first shown at night.
"Extra doner – just for you, bossman, it's on the house."
"Who told you about Izzat?"
The actual
turn occurs here, when we linger for a moment on this guy's fear.
Then everything we saw/heard to this point and after is then recontextualised as being fucked up.
We aren't just shown there's going to be a man burnt alive. It's sinking as much horror and vileness into the next minute it can to explain and then justify what happens to these people - including the children.
(1) They could've kept him hidden as the wickerman burns (a piece of tarp is covering just him, not the entire idol), but he's intentionally exposed to onlookers so they can
watch him writhe and scream in pain as he burns alive.
(2) The musicians stop when the bells toll to let people know the burning is about to begin, and then start up again.
(3) The flagellants continue to whip themselves, hinting the task isn't for some purpose of keeping evil subdued or some other grimdark-ism
(4) The mother smiles at the sight, and only looks away when her crying daughter yanks several times on her skirt
(5) The public orgy is revealed behind the back of the flagellants, creating the image of combined pain and pleasure - think Hellraiser.
(6) The daughter's crying is revealed not to be because she's upset at the events unfolding, it's because she can't watch otherwise, and is hoisted on the mother's shoulders,
jubilant and clapping.
(7) A chunk of the man's flesh falls to the ground, and the earth melts, corrupting it. The religious figure who initiated proceedings is confused before a demonic rose grows from it. He looks upon the burning man, seemingly unphased by it or already accepting of what's about to happen.

The comedic-if-gross scene from before of the man vomiting into the pig pen is now overwritten by what appears to be the same orc vomiting directly into the mouth of a pig
(9) We're shown in quick succession a bunch of images that can be linked together: The burned man's melted arm tearing apart, a man tearing into a piece of meat with his teeth, a pig on a spit over a fire, a couple at the orgy, the pigs feasting on the still vomit with one licking it from the face of the other, a close up of a man's mouth as chews messily on meat, before it's capped off with a burning man, whose eyes have melted and he lets out one last scream before the collective sin of the onlookers bursts out of his back as a hurricane of evil.
This is about everything we see within a minute before they're all karmically wiped out. This is a hedonistic cult celebration that has been so engendered into wherever this is, that it's become
normal enough to bring kids to – *cough* pride parades *cough*
Alternatively this is a completely normal and acceptable occurrence but they burnt the wrong sacrifice which is the sole reason everyone died at the end. There's another possibility why it's become normal in the context of the setting.
In the Divinity setting (at least from playing original sin 1 & 2) the 7 gods stole divine power from under their boss' nose, fucked him and everyone else off to a void (kind've a purgatory) and created morals in their own individual images because living things generate the power they feast on (Source). They weren't great morally but their biggest opponents (their old manager + the secret 8th guy they kind've fucked over but he's the devil so who cares) were also the biggest threat to mortals, so working with them was kind of necessary – not that many even knew what their true nature was in the first place. At the end of the 2nd game these 7 Gods are killed and their former boss (who has been continuously invading from purgatory from the very start) can potentially be locked away forever if you pick the game's most selfless ending - give up your source.
The elephant in the room with the events described is that the 7 gods are dead, the threat to the 7 gods is also dead/rendered a non-issue... but the
devil is still alive with absolutely 0 entities capable of countering or resist him. Whoops.
So with that in mind, we're seeing a world seeing a moral decline because the only being capable of exerting authority is evil incarnate and he has been growing stronger in the power vacuum since the end of Divinity Original Sin 2 (assuming they did the "give up your source" ending). In this setting God and the Devil are occupying the same role now, which is understandably a fucked up situation for everyone.
Regarding some handwringing over the trailer potentially being seen by children, unless you're of the sort that supports stuff like the Online Safety Act mandating age verification, all the sources to watch/view the trailer itself do specify the intended audience.
The Youtube video for the trailer say before it plays:
And the video is age restricted.
The Game Awards were also ESRB-rated.
I don't know whether the stream itself was locked to age verified accounts or not, but basically, the audience for the awards were expected to be of a certain age.
