In game footage is not the same as game play footage. Say you watch a video online and it says "made entirely of ingame footage", it can be accurate and still run into the follies of cut scenes. Bad offenders here are Battlefield 3 recently, but also much of the Max Payne 3 and Grand Theft Auto 5 footage. I want to see how it is to play the game, not how it will look like if I had a professional camera man filming me while I was playing the game.
To have a good counter example, the new Hitman game absolution, besides having some usually intense and just fantastic pre-rendered cut scene trailers, also includes a couple of game play trailers. There you can see a developer presumably, play through the entire first level of the game (or so it appears). You see the cut scene that leads you into it, then how the developer sneaks and murders his way through the level. No commentary. No popups or stops. Just game play. I for one applaud this.
The scam is that the game can look as good as you want it to look, but you will not see what those videos make you believe you see. They either show you exactly what you will see, i.e. the cut scenes, or things that happen out of a perspective that you as a player will never experience. Very disappointing in either way.
Sow me what we will see, for real, in the game. How it will feel like to drive, shoot and run through the city, battlefield and dark places. That will tell me so much more if I want to play the game than anything else.
