STARFOX ZERO (and puppets)
Forgoing the batshit crazy puppet intro, Starfox Zero for the Nintendo is a pure jolt of nostalgia - which seemed the theme of the Nintendo presentation. Super Mario Maker being a prime example that just falls short of the title.
The Microsoft Keynote had a lot of the new 'old chestnuts' - like Halo, Fallout, and Fable (all which looked amazing) but nothing was as impressive as the live demo of the 3D virtual reality Hololens presentation.
Horizon Zero Dawn is quite possibly one of the most beautiful games I have ever seen. The world building and character design is flawless. It takes the post-apocolyptic genre and pushes it farther into the future that we've seen before. Our modern society is no longer history - it is a legend, a whisper, a cave painting on the wall. The female protagonist, Aloy, is spectacular, skilled and smart (and fantastically voiced by Ashly Burch, from Life is Strange) as she fights the wild creatures (that are half machine) to survive in this open world gaming experience.
Shenmue III, which got fully crowdfunded over its $2 million goal within HOURS of this clip playing at the SONY Keynote.
