This is actually a good thread to bump up, because not everyone plays these games in 2017. 
The two standouts from this year for me were Breath of the Wild and Puyo Puyo Tetris (Switch version). I also really enjoyed Mario+Rabbids. There are also a couple of 2017 games that I enjoyed on the Switch, but didn't get a Switch release until later: Cuphead and South Park:Fractured but Whole.
Both Breath of the Wild and Puyo Puyo Tetris made my top 50 games of all time and are still in it. So, that makes 2017 a decent year for my gaming, but not exceptional. However, I realize from a sales perspective 2017 was an exceptional year for games.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
My Bet With curl-6
