I recently checked to see how many hours I've played new leaf (in the activity log) and wondered how many you all have played! If you'd like, you can share your time
I've played for 168 hours
According to my play log, nearly 400 hours. According to me town tree, however, I recently realized I'm still shy of 300. Which I know is pretty common (since I know it doesn't count a lot of things that the play log does), but I will admit I'm excited to see my tree grow to the next stage soon.
I've been playing since the game came out in the UK and I haven't restarted my play time every time I got a new town, so 1,752 hours and 40 minutes. :")
I have no way of knowing. ACNL is spread out over 10 cartridges (one of which died and was trashed) and about 15 3DSXLs. I'm certainly not going to try to find it all. While this may sound like a lot, I only started last January and on a really good day (unusual) 8 hours is max. It's 1020 now and I've been on two towns for a total of maybe 2 hours. Don't want to overdo it and experience "burnout".
I started playing ACNL on August 3, 2016 . . . and, as of this evening, I've logged 758 hours and 57 minutes with the game (according to the Activity Log on my new 3DS XL). Time well and happily spent, as far as I'm concerned!
