I know this has been discussed many times before, but hair length sliders. I want one particularly for Renee Jones-Brown's hair:
Because my hair is exactly parted the exact same spot, and is curly just like this hairstyle, but the only problem between my real life hair and this hair, is that my real life hair falls about mid/long, to my shoulders, as it grows like a weed.
I'm positive, they may get one in the next patch for Pets, since Pets involves hair sliders though, but this is not something I read, this is just my own personal predictions.
@Schipperke: Do what I do. Take a Sims 3 break for a while, and go back TS2, or another Sims Game. That's what I'm doing, until I install LN, explore the features, then take another break until town life or pets, whichever one you're more excited for. I would recommend Pets, since that will usually require a game update.
Also, I would love more food options. I know they come with WA, but if Sims 3 could fix it so we have more food options and quick meals, PB&J, Hot Dogs, and Lunch Meat Sandwiches should be meals even children can prepare. I want more dessert varieties for Sims 3 too.
What I really find really unrealistic: Vegetarian Sims who cheat, get sick ALL the time after eating meat. No real life veggie gets sick right away after not eating meat. I cheat on the holidays, (Thanksgiving and Christmas), or at huge events where I can't turn down the meat, and I'm okay. I know some get sick, some don't, I'm one of the ones who's been doing it (officially) since 09-10, and I have yet to get sick from cheating. I don't like how Holly Alto can't take from the meat tray, and get sick all the time. It's a life choice, and even Rachel Berry (who's a vegan), was able to eat a pepperoni pizza, without getting sick.
