What is different between sims 3 and sims 2?

I havent played sims 3 yet, but I have sims 2 and all expansion packs.
I think that the sims 2 is great but sims 3 normally has 更多 options.
So, i cant tell 你 that sims 3 is better because sims 2 is just fine!!!

In the Sims 3 你 can buy cars, Grim Reaper has different style, I think 你 can see what your kid is doing at school, 你 can see your adult sim at work 或者 any commutity lot, steal (be the burgular), change your sims style, and when your an elder your a ghost not packing up to go to death. I think those are the differences. 哈哈 I dont own the game but I seen vids on YouTube
