This is the thread I've been waiting for and didn't think to create myself! Thank you!! There is a lot of negativity around here and I love to see people just talking about their love, appreciation, or other positive thoughts on TS4.
I totally agree with @soko37 - I LOVE the addition of yoga! And I wish we could teach it too, that'd be awesome. I was just thinking about that the other day.
Another thing I love, from Get Famous, is Del Sol Valley. I am from the overall city it's based off of, and it's so spot on. I love that it doesn't snow there (with Seasons) and the sunsets are soo beautiful. The little details are awesome, like the airplanes flying overhead (I live close to an airport so this is especially cute to me), the pigeons, the graffiti on walls, the ALLEY behind some houses? I thought that bit was so cool. I've never noticed an alley in The Sims before. Also the random tourist Sims that show up are hilarious... although I do rock a fanny pack from time to time lol.
