"The man talking in the video says around minute 4 that it is a no spoiler video.
He also says that the grafics have improved a lot since the last time he played and that you can really feel the ff essence of the game.
He also says that the video is nearly always running at 30fps with very very very few drops.
Edit: He also says that the game is mainly an action game and that you van clearly see that from the beginning. But it does have some strategy: he mentions that there are many objects and strategies that can make a hell battle a cakewalk but viceversa can happen too if you wear the wrong things. But he says to not expect a strategic game, expect an action game with a bit of strategy.
Edit 2: He also says that the game is full with amusing and attracting content and that one of the things that attract him the most is the story which he says it seems very interesting
Edit 3: he says that the in game content is not there as a filling device but it is all there for a purpose and has been very carefully done. An example of this is fishing as he says there are various types of fish, there are different types of cebo(the worm you put to attract fish), and of fishing rods.
Edit 4: He says the combat is really good and it has lots of things to do, he recommends you to do all tutorials and to try to master it as it will make the game much better.(So happy about this as this was what I wanted the most from this game)"
anyway, i absolutely love the driving aspect of this game, seeing the mountains and clouds afar while the night comes... so immersive,
