Conversely, having extra time for gameplay does not automatically make a good game. It's up to the designer to make a memorable title. I heard MGS3 has a "climb the staircase for 5 minutes" gameplay segment. Surprisingly, people seem to appreciate the monotonous gameplay "timeout" to reflect on their earlier boss fight. Some probably hated the long and meaningless run (You can't skip it like a cutscene !).
In all cases, we will have to trust the designers to experiment. The cutscenes or gameplays are there exactly where they need to be.
I have no problems with brief cutscenes. Long cutscenes are on of my bitching points in a lot of games. Metal Gear goes far beyond the length any cutscene in any game should ever be.
Of course some games try to get on without them, like Assassin's Creed, where they lock you into a little area and you're forced to listen to someone talk. Those might be even worse, because you can walk around and everything, but you still aren't really playing, and a lot of the dialog is very bland. So it lacks the visual flair of a well directed cinematic, and it still removes you from the gameplay.
5 minutes walking up a flight of steps? That would bother the hell out of me.
Not if you can pause the screen and play with the camera.
I had read a bunch of things that mentioned full motion video. I just read up on the camera angles and that little robot thing. Is there going to be a mix of in-game cutscenes and full motion video, or is the whole thing in-game?
