Microsoft E3 montage videos analysis over the past 4 years

We all know what we see from E3 is by no means the final product. Companies show off an early build if not a pre-rendered video to at least give us an impression of the game. These are understandable circumstances but how many years have we been shown pre-rendered footage to pass off as actual gameplay?

"In our first segment of this E3 edition, we take a look at the Microsoft E3 montages (one montage) over the past 4 years; one of which was done in house, and we can see what stayed true and what was just completely off."

The story is too old to be commented.
