My favorites of the decade, not necessarily the 'best' games by some critical standard (though they were all very good):

1. Kingdom Hearts: Birth By Sleep (2010, PSP)
2. Mass Effect 2 (2011, PS3)
3. The Last of Us (2013, PS3)
4. Pokemon X/Y (2013, 3DS)
5. Assassin's Creed IV: Black Flag (2013, PS3)
6. Fire Emblem: Awakening (2013, 3DS)
7. Super Mario Galaxy 2 (2010, Wii)
8. The Legend of Zelda: Breath of the Wild (2017, Switch)
9. Super Mario Odyssey (2017, Switch)
10. Batman: Arkham City (2011, PS3)

2013 was a very good year for games. I also notice that most of these I played before I had kids, and the other two were Nintendo games I played with them.
