I only have Zelda and Mario Kart; Zelda is at around 120 hours and Mario Kart maybe 15 hours. My three year old daughter has probably put another 20 hours on her profile for Mario Kart as well.

I rented Arms, but I didn't care for it very much; I'm not a big fan of fighting games sans Smash Bros.

Breath of the Wild: Over 120 hours. I got all of the shrines, 90 percent of the side quests, and an ok amount of Korok seeds done on top of the main quest. I forced myself to stop playing so I could do everything on hard mode (which I will do when I am done with Disgea 5).

Mario Kart 8: Over 10 hours. I play online with friends and sometimes with the family.

Lego City: About half way through with over 10 hours. I pretty much play the co op only with my stepson.

ARMs: Over 20 hours and climbing. Currently my main online game until Splatoon 2 comes out.

Disgea 5: Over 35 hours and climbing. First time playing it and loving it. Currently my main single player game.
