I enjoy the game very much at the time, but that's also thanks to my rigid and never ending systems and notes on the side line. It keeps me busy running a community where each world is a district within a political region, and the past weeks I've created the past of several nobility houses, just to flesh out the region's history even more than I already did. I have a working council with elections every 5 years (where I don't really decide or know the outcome in advance, so it adds some excitement), I have lots of companies where I keep track on owners and boards etc, there is a bank and I keep notes on loans and stock investments, and there are other jobs that are technically not part of the game (ie Janitors). Whenever I get a new pack added, the added content is often meh, but it always adds spice to my ongoing universe - like University is not that exciting to play, but those getting a good degree will do better in my community - ie in elections, and they will probably do better economically meaning they might become central owners in some existing company, or perhaps being able starting their own.
I too need a break from it all occasionally, but I always get lots of new ideas when I'm not playing, so in fact I'd wish it would be easier for me to stay away for a longer period in order to focus on other projects :)
