With production values that rival many Hollywood movies, this trailer brilliantly introduces the high tech, dystopian world that Adam Jensen lives in. It's breathtaking stuff, and holds up to even the most legendary sci-fi classics. Possibly the greatest video game trailer of all time, it almost seems a shame that we didn't see a feature length film based on this trailer alone. Are there any other incredible video game trailers that you enjoy watching? Do you disagree with anything on this list? Let us know in the comments below!
