TBH I've been almost forgetting to play the last couple days and things are becoming a chore now that I've accomplished most of my goals, but this is what I expected and what always happens in AC. May step back for a bit and come back in force in a few months, depending on updates.
Interestingly, I'm petering out right when I've passed my New Leaf playtime total (325 hours), and that was over 7 years' worth...
