The Legend of Zelda: Breath of the Wild was my number 1 as well. Love the freedom, the numerous possibilities, exploitations, stat buffs, and the whole sense of journey and growth. The orchestrated music was on point during cut-scenes, and there were serviceable in-game tracks. Unfortunately, I didn't feel anything from the combat themes. They were the most disappointing songs from the soundtrack. They were neither blood pumping, nor dramatic, just present. Play-control for the game was good. Took a while for me to adapt to things like having a jump button and the new ways of accessing tools and weapons, but I caught on eventually and the controls became invisible to my experience. For a sequel, I'd love to see further improvements to combat and enemy variety, plus more full scale Hyrule Castle-like dungeons.
Nier Automata was a pleasant surprise for me in 2017. I was a bit disappointed with some of the characterization of our three main androids and the criteria necessary to experience the full story, but the great music, play-control, and action packed boss fights kept me very engaged with the game in my play-through. Glad I didn't skip the game. Was originally not planning to play it due to the original game having strong swearing and characters I couldn't enjoy, never mind the mediocre game-play. Nier Automata demo was what ultimately convinced me to give it a chance, as the game-play was on point, and I was hopeful 2B's whole robotic 'don't show much emotion' angle would allow me (the player) to carve more of her character to sync with mine.
These two were probably the most memorable of the year, for me. I've got enjoyment from many other titles as well, but they didn't stick to mind as much as these two did.
Overall good year for gaming as that top 20 shows. I agree with a good number of those picks.
