Is seasons worth getting?

Yes. Despite some bugs that they are working on, this is overall the best pack so far. All worlds look gorgeous as the seasons change, the calendar and holiday thing is cool (even random holidays pop up from time to time). I like how in the fall, I been noticing trees changing colors gradually and now many are like a reddish color which is nice. There is a lot to do and a lot of new items plus new career which is similar to the careers in City Life where you have the option to just send your sim to work or work at home.
