Apart from bugs and annoying phone calls every five minutes (especially those of the "Congratulations on making friends with your own daughter, she's a really cool person even though I've never met her and don't even know the colour of her eyes" kind), TS4 has a habit of being either too subtle or too in-your-face about everything. An example for the latter would be the overabundance of townies with Asian names that came with City Living, bonus points if their ethnicities don't even match those names. It's not like I don't want that in my game, just... not on every other person I meet in public even outside of San Myshuno.
