Late to the party, but I still caved in sooner than I thought I would.
I have mixed feelings about the game so far. Parts of it remind me of earlier sims games, for better and for worse.
I
loathe the camera zoom. It's really jerky and even though I have the option checked for TS3's camera, I still can't get a handle on the controls. Put it on my "to learn" list. I also don't think I'll ever fully get over not having Create-a-Style. My sims' clothes don't entirely match and it hurts me on the inside.
Don't know how I feel about the transition from LTWs to aspirations. I didn't really pay attention to them in TS2, and I last played that game in 2005 anyways. It does seem to "fit" the game, though.
A lot of the interactions are cute. The sims in general look pretty nice, even if the facial sculpting options are limited, and the base-game fashion isn't godawful for once. Money and needs seem more challenging, which isn't necessarily a bad thing.
A lot of this sounded negative, but I'm also hopeful that I'll find more things that I like as time goes on.
