Breath of the Wild - I wasn't surprised this would be on Switch at release, but its reveal at E3 2016 was a huge surprise, and it was cool that Nintendo let it be the focus of their entire E3. After several years of the failed Wii U, they revealed this amazing Zelda game. And after watching hours of E3 footage, I knew the Switch would be successful and I would get to play a Zelda game I'd enjoy as much as the NES/SNES days. I literally waited 25 years for this game to be released.
Honorable mention goes to Hyrule Warriors: Age of Calamity and Cadence of Hyrule. Both are great games.
