While yes it takes a lot of time to make a game the indie scene isn't interested simply because of unity's dominance.
The AAA scene is using their own engines or the unreal engine. While you can switch engines when creating a new game the incentive isn't there when you either already have licenses for the unreal engine and a small army of programmers who have mastered it.
People were expecting a shit to Unreal when they decided to make it free for education/take a 5 % cut. This shift hasn't happened...
I believe the game Streamline, released November 18th, is built with Lumberyard and makes use of its Twitch integration. This game's studio had support from Amazon.
