What are some fun free virtual games for the iPhone 4?

I really want some fun virtual games! Particularly like Yoville. Where you create your own life and things like that. I've looked everywhere, but I can't really find anything. Also most of the games I play aren't the full version.

This game isn't really like Yoville, but it's really fun - and free! If you like games like temple run, you'll like this one. It's called "Whale Trail" and just like temple run it's continuous (never ending) and VERY addicting. Have fun!
