I feel like there's something people are overlooking with BOTW; it was the first time that a complex, HD/AAA open world game was playable on a handheld. That in itself is a pretty significant breakthrough for gaming.

That's groundbreaking for handhelds. Groundbreaking for gaming is figuring out how to map FPS controls to a gamepad, creating the platformer genre, or adapting 2D to 3D.
