2011 - 106 hours ( bought the 3ds at december, so spending over 100 hours in 1 month is pretty good) 

2012 - 200 hours (didnt bought any new game)

2013 - 419 hours ( Crazy year)

2014 (so far) - 229 hours ( i think it will only reach about 280 hours, because of the wii u) 

I don't need to check, I know 2013 is my most played year, I spent over 90 hours on Fire Emblem and 70 on Animal Crossing that year. And that doesn't include everything else I played. My playtime so far this year probably comes to around 100 hours. My Wii U has been one reason for this, playtime for that is 60 hours in October alone, at least 15 to 20 hours every other month apart from July when I was in Canada.

I'd guess my 2013 playtime for 3DS comes in around 250 to 300 hours. 

EDIT: Out of curiosity I checked.

In my defense on steps, I usually never leave my 3DS on when I go out with it.

Believe it or not, 1,000 steps is actually pretty easy to get.  Having your 3DS on you and walking for about 5 or 10 minutes would easily get you 1,000+ steps.  :P
