I was thinking about intros lately, and there are loads of great cinematics and CGI shit out there, but at some point i still want to be in control of my character all the time, even while story telling on introducing me to environemnt, story ect.
Thats why in terms of idea Valve and Half Life one is the best intro out there (execution is the Black Messa - love it !)
All the time i'm in control of my avatar, i'm introduced to the Black Messa facility, times it takes place, i know who is my avatar and i can learn the environment by my self. This is great, far more gameish than superCGIshit - i would love for games to walk away as far as they can from cutscenes/cgi movies ect, and let me be in control of my character all the time. This is the same for story telling IMO.
