On my old 3ds data which I now have on my 2Ds, from 2015 until now I have played about 1,000 or more hours onto playing ACNL. I've become addicted to it ever since I picked it up at Gamestop for the first time. :')
My main town has moved to different 3DS since the release date and I have more than one town. My total is over 11,000 hours.
Right now I'm just playing my main town each day for one hour. The rest of the towns are frozen.
877 hours. Originally I had added up my times played by accident, and was thinking "Oh, 480? That's not that bad." But then my actual play time is like double that lol. 491 on one game, and 386 on the other.
