What do you miss most?

i miss the ambitions (literally) devs had with the game, the game is full of content and it brought lots of new features & concepts, it has its flaws of course but the good surpasses the bad. ts4 also has good things, but sadly it seems to lack any kind of ambition, i don't know if it's the budget, or if devs are afraid of messing too much with the game, but ts4 still feels empty despite all the packs, because more than adding new content they recycle it all, to a point where it gets boring to see the same things all over again, the same animations here and there, the same sims with a different face, etc.
