For me, I play in a very bright room with a skylight that shines down on my screen. I'm pretty sure glare from the lightbar is the least of my problems. But I do understand the concern. When I had a dedicated gaming room, I had taken a lot of care to set things up correctly and would have been more than a little annoyed if there was bad reflection on the screen from the controller.
“With the very first prototype,” he tells us, “we had the light bar more out, so that you could see it from a top view. But several people mentioned that a lot of gamers play in the dark, and they don’t want something to be too visible. If it’s too bright and distracting, it can break [the game experience], especially if it’s a horror game. So we made it pretty subtle, more secondary.
