Amazing and unexpected with one of the characters ,an american sounding voice commentating through the entire thing. Def unique trailerwise. The team who made the trailer really went all out and weren't afraid to show all the things you could do in the game.
I love watching crowd reactions to Resident Evil 7. The logo design was sooooo clever.
I also love Tekken 7 trailers, it's just badass when the portraits appear with their names in their stylized font behind with the ease out animation and then the badass Allucard announcer saying their names. I saw the Season 2 reveal live, during EVO 2018 and it was soooo epic.
I also love Guilty Gear Strive reveals.
Infamous Second Son was also cool, with their Nirvana cover.
The trailer for New Pokémon Snap! I loved the original and played it all the time when I was a kid, and I'd been hoping for a remake or sequel for the longest time. Seeing the new trailer was a dream come true
For me, it was the trailer for Skyrim. Most people roll their eyes at the game now considering how many platforms it's been remade for, but, back then, that trailer drove me crazy. Even to this day, I still listen to the song.
