For people with 1000+ hours on TS4 -- What keeps you playing?

I have 4188 hours played.. can't really say what keeps me playing besides just liking the game. If I didn't like it then I wouldn't play it.

I will go for periods without playing it at all though. I stopped playing around the time Cats and Dogs came out and only started playing again when Seasons was announced. That's been the case with me since I first started playing The Sims (around 2003). In fact, I stopped playing The Sims entirely in 2008 and didn't start playing again until around 2012, 3 years after TS3 was released.

I'd love to know how much time I spent on TS2 because I seriously loved that game. Haven't played it for 10 years. :'(
