I was watching this video: I learned that the way companies depict the games at gaming conventions serve to increase our hype for a game. However, in reality they give us unrealistic expectations from the game and makes us sore if they don't deliver. Many of the games shown during E3 were deliberately shown to have better quality just for the purpose of showing off the graphics and many were only CGI animations. There is no guarantee that they will deliver exactly what they show. How can we trust companies anymore to deliver what they preach?
