1. "The Legend of Zelda: Breath of the Wild" (2017, Nintendo, for Switch and Wii U)
With "Breath of the Wild," Nintendo didn't just set its foundational adventure series in an open world for the first time. It deconstructed "The Legend of Zelda" to a degree greater than any game in the series since 1987 sidescroller "Zelda II: The Adventure of Link." It turned exploration into a test of resources, combat into harrowing chaos. It can be bypassed almost entirely, or you can spend hundreds of hours scouring its gigantic, painterly landscape for elegant puzzles that guard the power-ups you might need for the endgame. It tells a moving story of triumph in the shadow of failure, not only making some sense of "Zelda's" complicated timeline but penning some meta-commentary on the act of playing a video game itself. It's the game of the decade, and it's not all that close.
