You should not have to leave a game to learn a game.
You don't, the video's play in the arena message side window while you are in-game. When you move to the next location, by clicking on-line and even off-line, or the hanger, the plane etc. the video follows and the next segment starts. For me, it required a fresh install to see these, but as I said in an earlier post, my login+password did not interfere with seeing the videos.
My biggest complaints with some of the videos are the distraction of the music and engine sounds in the planes while trying to fly and listen at the same time, and the fact that the controller mapping overlay for the Oculus touch disappears. Which control handles gear and which flaps again? A toggle for reactivating the overlay would be useful, along with clarifying not to launch when first entering a plane until the lesson ends.
The video's play in both the standard and VR versions, and they can be disabled with checkboxes or by dismissing the arena message side window.
You've got to hand it to Hitech. He's attempted all the useful ideas presented over the years to capture new players. Just because you can't see them doesn't mean he hasn't listened and acted.
