You'll like the in-game recordings.
I just sampled a bit last night. Is she a 1000 year old demon?
I really thought she was a kid.
It's so good, right? I couldn't believe I put over 10 hours into a 1.5 hour demo and really liked almost all of it. That said, things that bother me that I hope they fix in Phantom Pain but have no faith that they will:
1) You can't fall/climb down/drop off an elevated ledge while in prone position. This is super weird when you are crawling along the top of a roof or shipping container and have to go to kneeling position to drop off of it. This has got me seen so many times.
2) The first person perspective is positioned to the the center of Snakes pivot point/model instead of his head. This is a real point of contention because you can visibly see Snake's head/eyeline above a piece of geometry, then when you go to goggles, the view is blocked. I would position Snake over a bit of a ledge by crawling over it, so his chest was resting on the slight elevation and his head was clearly above the geometry, then go into first person and it's clear the camera is positioned at Snake's waist. This is such an oversight for the attention to detail that I'm used to on Kojima games.
Well, now that is gonna start annoying me now that I know that.
