So far I've noticed they added new instruments, which only makes sims more of a grindfest. They also added vampires, who aren't that much different from the regular sims and the apartments are usually so small you can't fit anything in there unless you cough up like 100 000 simdollars for a condo. Also, astrology signs that don't seem to do anything and celebrities.
If I missed anything, please tell me.
