In 2015, easily one of the most "holy shit" conferences ever, there was yet another trailer for No Man's Sky. Again, it wouldn't ship for another year and change. Horizon: Zero Dawn showed up for the first time, supposedly set for 2016. It moved to 2017. We then had a first look at Media Molecule's Dreams, a strange creation tool without a release date, but the promise of a beta in 2016. 2016 came and went without a beta, and it's unclear when the game will be released.
This was also the event where Yu Suzuki announced he was making Shenmue III, a game that's supposed to ship in December but won't even be at E3.
