3. Grand Theft Auto IV
https://www.youtube.com/watch?v=M80K51DosFo The best of all Rockstar's promotional videos, the 'Things Will Be Different' trailer for Grand Theft Auto IV made it clear that the company would be taking a bold new direction with the fourth game. It also showed off a remarkably realistic-looking world, and the use of Philip Glass' music made it hard not to buy into it all. As said earlier, the Grand Theft Auto series is all about the amazing worlds on offer, and this trailer does a great job of showing off just that.
