It's just one of those things you kinda have to get over with kojima trailers. It's expected he will show a trailer in a motion picture style of story telling, not actual HUD and gameplay. I really dont care as long as he keeps up the great work. I dont need gameplay videos to validate what the game will look like, with kojima trailers you kinda just know what hes aiming for and what he will achieve in the final game.
But I dont knock you for wanting gameplay. I just dont get riled up when he doesnt show gameplay, because I already don't expect it.
trust me... I'm far from riled up over it.
I just don't know why he spends the time making these productions rather than setting up a little game code for us to see (unless game code is not ready yet).
Other than the fact that (as was mentioned earlier)... he's just a frustrated movie director.
