The Sims 3 is a great improvement on the Sims 2, the customization options are huge on both your sims and home, the interactions are entertaining and with each expansion pack it just gets better. Commonly the series is known as "digital crack" because you could be doing the same thing over and over and still want to play it. The only problem is that there's so many glitches and bugs, like a lot of EA games they're pushed out with these bugs so getting the game in it's first release would have lead to disappointment sooner or later when you notice the problems. And now they're bringing out the Sims 4 it can be expected that a number of bugs would be left untouched in the game and it's expansions. I think it's worth it as a fun way to play games but it's no where near perfect, needs more polish.
