I felt the same way about the Sims 3 at first. I thought it stunk. Then I played it for awhile. The game is so much more a game. There are millions of things a sim can do. For example, just in the skills a sim just doesn't master a skill. He goes beyond that. He needs to use his mastered skill to reach more and more levels of mastery. It takes a very long time to reach the top. there is no way a sim could master to perfection any skill unless you would disable aging or put the lifetime to epic. The challenges are quite entertaining too. I thought the sims themselves were butt ugly but I have been able to create some very realistic and beautiful sims ( and believe me, I'm no modder!). I've also seen some beauties on the exchange and other sites. EA told the truth when they said this game opens up your sims to an entire world.
Give it a chance. You'll never know unless you try it.
ps. I have uninstalled the Sims 2.
