How do you keep your game play entertaining?

I focus a lot on community matters. I have a working Council, and 5 years elections, even political parties (not played very detailed though - but I made a system involving the N.A.P.s. I also have nobility and 225 year of history for most of those families. On my website I have a profile page for all my 300-400 sims, all connected through a huge interactive family tree. I probably could have listed few more aspects, but main point is that I can play in so many different ways, it will never get boring. Whenever I need a serious break, I can work on builds or historical portraits, to fill some of those gaps. And if I want to close the game completely, I can add features to the script for my site/blog. In a way it has become way more than a game :)
