Rockstar never gives BS shots. The angles are obviously specifically picked but its real time and had plenty of gameplay. That trailer is mind blowing. Leaps and bounds ahead of anything graphically. It looks like a game from 5-10 years from now.

Real time to me isn't in engine cutscenes. It's actual gameplay from the same viewpoint you use in the game, walking, driving, shooting or whatever.

Like you said it looks like a game so far ahead of all other games, that's precisely why it's hard to believe. Maybe they just have the budget and time to put so much detail into every nook and cranny.
