My question to you is what do you think the best Trailer ever is? By trailer I mean a trailer to a videogame or a movie etc., not what you go camping in. Personally my favourite trailer of all time so far is the Dead Island videogame Official Announcement trailer, that trailer blew my mind and made me depressed. It's powerful.
