There's a few things about the game i would change.
1. Teen heights, i just don't understand why they'd have teens and YAs if they're practically the same. Yes Parenthood did improve them a lot, but sometimes there's just not enough of a physical difference.
2.Babies , babies are another one of those life stages that need improving, first off it doesn't help that they only get 3 skin tones and 2 outfits, then to top it off they can't be moved away from their crib. I'd get rid of the baby being tied to the crib and give them changing tables, strollers, ways to bathe and entertain them. In my opinion toddlers in ts4 are too old for changing tables and strollers.
3.Bugs/Glitch Testing, One of the things that really irks me is that they don't test for bugs as good as they should, For example there's tons of floating objects In worlds like trees/lamp posts and there's missing buildings in San Myshuno.
