It would be nice to get more Maxis-made sims and lots for our library. Some of the sim families I would personally love to have are:
Rebellious Vampires, The Noble Vampires, Malpractice, The Freelancers, Celebrate Diwali, New Politics, Princess Cordelia, The Landgraab Family.
Also we need more lots of different sizes, not just 30x20. These are some I would suggest:
Bowl More Alley (40x30), Moonlit Vampire Escape (30x30), Shimuzu (40x30), Outdoor Movie Screening (40x30), Ultra Splash Lounge (50x40), Lord's Garden (50x50), Sweet Lloyd's Tarts (20x20), Levels (20x15).
And lastly, could it be possible to have all the CAS sims in our gallery? Sometimes we need to find a particular one and it can take a lot of time to find it. I've been looking for Tristen Palmer and I must have clicked on "reset household" at least 300 times and still didn't get it.
