Zelda Breath of the Wild. Enough gameplay to know what to expect and keep the hype. not a trailer or a 10 minutes of (we have something) gameplay and a dream release date.
Zelda is getting an insane amount of coverage in mainstream press like Verge, Los Angeles Times etc. Even PC Gamer jumped a gun and made a thinkpiece about it.
Despite me having no plans to buy any Xbox hardware I enjoyed the MS conference the most. Nintendo's 40 minutes of Pokemon was downright painful, but Zelda was looking great so I give them second. Sony's did basically nothing for me. Lost even the interest I had in Horizon.
