Some parts of the DS trailer are actually playable such as the Ocean part so it further cements how ludicrously good looking this game is. Death Stranding is a what, 3rd gen Decima based title with additional artistic tweaks from Kojipro so technically speaking it should look better than Horizon ZD on the get go. And this time they would probably have concentrated more on the Pro hardware on the get go to accommodate more complex lighting and visuals than HZD ever could. The more cinematic direction of Kojima also adds greatly to the general appearance of the graphics oomph. I'm not saying the final gameplay is necessarily 1:1 to the trailer quality but it shouldn't be too far off either.Cutscene in realtime:
The area is not so big in Death Stranding after a few meters the fog obscures everything.
It's not just the tech but how the scenes are filled and in predefined cut scenes it is a snap to do it better than in gameplay as long as you put enough time and effort into it.
