So yesterday I decided to resurrect a few of my older games. I couldn't get my need for speed most wanted working as a disc was scratched and would install

So, I decided to reinstall my sims 2 base and expansions.
I used to create and modify things for my game using a lot of different software, and things like that so, it seems like I might go back into doing that.
aaaanyhoo, I have seen Sims 3 online, but it seems there aren't that many changes in the game between 2 and 3. Has anyone played sims3? is it worth it?
