I never got into the Sims, or played any other version of Animal Crossing, but in the months I've been playing New Leaf, I haven't felt any desire to log in. I make myself do it. It's really an eye opener about what I get from SL (or got). A bunch of AI and shopping from one store, plus decorating from found objects, is giving me the same satisfaction
I love SL too. I just don't feel the need to be there right now. I used to want to log in every day, but ACNH is filling that need. And I guess that's weird. I guess I should get out more
