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.
Kane & Lynch 2 Dog Days - War Junkie - I love the contrast between the rough and shitty situation of a dude who can't let go of criminal life compared to a psychopath who managed to get his life together.
FFXIV: A Realm Reborn is a fantastic trailer but it's almost cheating because Answers is such an unbelievable Uematsu banger that it carries it on music alone.
