I've been playing for two years and I ain't even close to not checking it for a day.
I've been playing a second town since Christmas. It's been enjoyable to get a clean slate and re-read all the dialogue. I didn't do this out of boredom, but rather lack of motivation to re-design the main town (which I'm still avoiding). I understand where you're coming from, but this game is more than level ups and events for me; the struggle to have that "perfect" Springfield (i.e. design). I'll always have something to do because my town can always look nicer and, to me, that's just as important as new content. I won't be satisfied until every last tree, flower, lamp post, etc has been properly placed and that day is nowhere near.
I love playing this game and play daily. The only thing I would say against it is I think the events go on far to long.
