A:Answer Google Play movies, yes. It's actually quite nice - I use it to watch movies in bed at night while my wife's sleeping. You can be in a dark room without disturbing anyone, and it's like you're looking at a 200" television screen. You can size the screen up and down to a comfortable size. You "lock" the screen in virtual space where it's easy to see when you rest your head. Once "locked", you can turn your head to the side and not see it. For example, you'd "lock" the screen in front of you. If you turn around, the screen will be as though it's behind your head. As you turn, the sound shifts from left to right as well. I like it, and the video quality and picture are quite good. Two things - you have to have a "Daydream ready" phone (Google Pixel, Pixel 2, etc.), and have it charged up, as the Daydream App uses a lot of power. Also be sure to use nice headphones (I use bluetooth over-ear headphones). Movies can be streamed, or you can download them to your phone for offline viewing on a plane. You DO have to download them to your phone ahead of time, and have storage to hold them, of course. One thing to consider is that with the DayDream and headphones, you really are isolated. If someone tries to get your attention, they'll have to touch you, since you can't see or hear what's going on around you.
Can't speak to sports games - you'd have to google around and see if there's a VR app for that.
