I play in far longer bursts. With Wild World I played it for about three months straight, then put it down for a few, then another three months and so on until CF came out.
With CF I played every day for a year, with the express purpose of meeting all of my goals:
-Perfect town (and maintain it!)
-Wide variety of hybrids (all of which are currently within my house, my alt's house, and their closets)
-Completely filling the catalog (sans things like the yearly New Years shirts or some of the region exclusives)
-Upgrading house and paying it off
-Catching every fish
-Catching every bug (god damn you tarantula)
I probably could have played after that, but I felt satisfied in finally putting it down after so long. There were some spots where I just didn't like it, but overall I just loved the experience.
I am eagerly looking forward to the 3DS game~
Maybe I'll boot it up one more time before the 3DS game hits, see how everyone is doing...
