Unfortunately, the Sims 2 is plagued with a problem that renders it unplayable.
If you play a Sim long enough, eventually they can no longer chat with other sims. Which unfortunately means they can't do much, since sims chat a lot in the Sims 2 (while eating, in the hot tub, watching TV, relaxing in bed, etc). Just can't do those actions any more.
Not everyone has it yet, but they will get it, if they play a sim long enough. First reports showed up about a week after the game shipped, around the 22nd of Sept or so.
So for some people, the game has been unplayable for well over a month.
There are also some minor issues, like with the Teddy Bear, but they are minor.
