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

4262 hours is what it says for me. No clue how much of that is playing, pausing ect. I know I even play offline sometimes so whoops.. I really don't know how much time it's been but I know it's been a lot.
All sorts of things keep me interested. I play different ways from get ahead and play nice to deviant play. Sometimes I try self challenges. Sometimes I want to see what the new packs bring and just focus on that for awhile. Sometimes I go on mod binges just to see what they do in the game then I pull them out and play vanilla. I tell stories to myself as I play and structure out their lives to make stories. I love going in CAS when inspired to recreate maybe the cast from a tv show or movie or redo all the Sims 2 characters and worlds I loved and give them new or updated stories and housing. There's just a lot of ways to play from intense and focused to casual and light.
My desire to play can be cyclic also. I take breaks if there is no draw for awhile. Then it comes back strong.
