With many of the recommendations in this post, this is what my game looks like, and I'm happy with it. I personally think The Sims 3 has a lot of potential. But if you fundamentally dislike the style, there's only so much that can be changed. There are many mods that can improve the appearance of sims and the environment. The graphics of The Sims 3 now look dated to some - even when it was new many people disliked the style.
