I've been playing since it came out but I've gone through phases and taken breaks... I'm not back to full blown obsession lol. How long have you been playing ACNL?
June 12th, 2013! Had some breaks in between but usually I was very constant. Somewhat recently (December 13th) I started a new town on a new cartridge, but still gathering up courage to delete my old town (that I don't play anymore but... ): )
I've been playing since the spring of 2014, and New Leaf is my first AC game in the series. I've been pretty obsessed since I've gotten it, so the longest I've gone without playing it has probably been around a week.
Since the first week of July 2013, I took about an 8 month hiatus when I got frustrated with my original town and then had a baby... now I'm right back to obsession and have even picked up a second system and more towns... I try to play other games sometimes, but its never as appealing. I went animal crossing in 2007 or 2008 and have been ruined for other games since...
On the 1st of march I will have had my town a full year, but I was on again, off again. I had long breaks, short breaks, and months of full-blown obsession.
