I have rewatched MGSV trailers multiple times, and I find this combination of 5+ minutes videos with scenes and music building the right atmosphere to be amazing. The other thing is, that for some, they created fake expectations of what story was going to be about.
Death Stranding first trailer is also great, it’s just one scene from the game, and you have no slightest idea what’s going on.
The Mechanicus trailer is maybe the greatest ever.
I also fondly remember the Skyrim reveal trailer, because the music was so epic when I saw it for the first time, in ancient times.
