Assassin's Creed Revelations
The Witcher 3
World of Warcraft
Halo 3
Dead Island
Each of these trailers, while still old, are my most memorable trailers. They all brought out an excitement I never thought possible from just a trailer. I mean we see game trailers all the time but THESE themselves were outstanding. To me at least.
Anyways, now that you know mine why don't you share yours below?
