Well, I finally decided to purchase an expansion pack for The Sims 2 awhile ago. After reading up on them I decided on University but it wasn't available so I bought Pets instead. For the thirty dollars, it was a big mistake.
Don't get me wrong. The game is fun. It's just not worth that much money. You get a few new pieces of furniture and buildings items of course, and you can create cats and dogs. The selection when it comes to making these animals is fantastic - there are tons of different colors, more eyes for cats than for humans, and most, if not all, the species are available.
You can give your animals three different jobs: security, pet superstar, and another one I can't remember. They live for a long, long time...almost as long as the average human actually, which can get annoying after awhile. You can train them to do tricks and enter them in pet shows.
But pets are a lot of work. If your Sims don't want a cat or dog, then there's not much else to the expansion pack. You can buy a bird cage or a gerbil but you barely see the animal. There are no other choices. I was kind of hoping for reptile varieties and maybe some weird things, but Maxis decided to end it there.
So, unless you plan on every family owning a pet (and I repeat, it's of work), then don't spend your money on this. There's just not enough to it.
