Still haven't looked at any of the promotional material, there's no point in watching the ultra polished curated content that isn't really representative of the grand majority of gameplay.
Eh, it showed off mission setpiece stuff that's just another iterative improvement over the same things in GTAV and RDR2, gunplay that's still mid but looks a bit better than GTAV's, driving that's another iterative improvement over GTAV, and cutscenes that are a bit more modern. It's nothing unexpected or unrealistic, and would have been solid but still not groundbreaking even if they'd managed to have it ready a couple of years ago like they'd initially planned.
I hate that rockstar still almost exclusively targets the console market even as "wot if you had a shitty, locked down PC that you had to pay to use online" is dying as a concept because the manufacturers aren't willing to make them heavily subsidized loss-leaders to trap people in their ecosystem anymore, because it looks like it'll be pretty good.
It's also a shame they're not doing physical releases because everyone should only steal it.
