So far since getting the game in January this year I have logged 73 hours but again like Cosmic Kid, not alot to show as I have reset it like 4 or 5 times due to laziness
New Leaf is the ONLY game that surpassed the 1,000 hour mark on my 3DS (1424 last checked) and 2DS (1011 last check), and on the New 3DS it's just begun at 30 hours. The 3DS LL has just under 500 hours (468 last check), so you can do the math to figure out it's around 3,000 hours, which now that both towns are established, and I don't need to play more than an hour a day on either, should allow for more time for other stuff (hopefully).
