If players of The Sims found interesting companions through playing The Sims: Unleashed, those who play the sequel to the wildly popular game will have an equivalent set of friends - from the dog world, this time - in the new expansion pack, The Sims 2: Pets.

Not only will you guys have the chance to choose from a variety of existing breeds and hot designer mixes, you'll also be able to customise your pets by choosing their body shape, unique markings, and even their personality (one area where games like these put real pets in the shade). As in real life, your Sims' pet also needs to be taken care of and trained. You don't want to come home to a clawed-up new couch, don't you? You still have to put your foot forward and let your new pet know who's the master of the house.

Of course, you don't want to be just a drill sergeant to your pets, so you'll also want to teach them to shake hands, roll over and play dead, spend some play time with them, or perhaps go shopping together and grab some cool pet accessories that will make the neighbor's dog go green with envy. All of which you can do in this game.

The Sims 2: Pets will be available on the PC, PS2, GameCube, Game Boy Advance, and Nintendo DS. A version for the PSP will follow. What's interesting is that there will be unique features for each game platform.

The DS version will have a "Manage a Pet Care Center" feature where you can pamper, preen and nurse your pet at your very own Pet Care Center. You can also earn extra Simoleans by selling pet products in your shiny new pet shop.

The PSP, PS2, and GameCube versions allow you to take your pet for a stroll at the Central Town Park. And while you're at it, you can drop by the Town Center and shop 'till your pet drops.
