I think that the Sims 3 World Adventures isn't so inappropriate.
The sexual stuff isn't so bad. I bet your kids see a bunch of sexual activity on TV that your watching. It won't be the only time they see it happening.
Other ways, if they had the talk, it won't be anything new to them.
It's a fun game that your children can enjoy.
My kids love this game, but I don't let them play it ALL the time because, I don't want them to get addicted.
There is NO drinking in this game.
Your kids probably won't be asking you about Woo Hooing and all of that if they know what it is.
