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 most excited I have ever been for a trailer was when I saw an ad for Secret of Mana on TV; and it’s entirely because it was the first time I ever saw a video game advertised on TV and not just in magazines.
