If you have played the other Sim games, this is pretty much the same. Sure, you can kill your sims, but why would you do that? That's wrong. You can now own pets, you can feed them and take care of them (actually you have to), and best of all they can have puppies, or kittens! I think that Sims Unleashed teaches some responsibility, to show how hard it is to keep pets, and a whole family! Just beware that there are some bad uses for the game. Don't abuse a great game!
