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 Battlefield 1 trailer.
I had never played a Battlefield game, and that trailer got me pumped enough to buy it at launch. Also, WWI was such an interesting (and horrifying) war.
