The Sims: Unleashed

"The Sims: Unleashed is the fifth expansion pack developed and published by Maxis/EA for The Sims. The Sims 2: Pets, a similar expansion created for The Sims 2, is inspired by this expansion pack. In Unleashed, the Sims can now adopt pets for their families, particularly dogs and cats. Dogs and cats are treated as Sims, while other pets are treated as objects. However, they cannot be controlled directly like human Sims are. Furthermore, Unleashed introduced gardening, allowing sims to grow and nurture plants that could later be harvested and consumed. Gardening was re-introduced into the sequel in The Sims 2: Seasons, however is already present in the base game for "The Sims 3".

In Unleashed, the original ten-lot neighborhood that was featured in all previous games is now expanded to over forty and there is now an option to re-zone lots into residential or commercial. In commercial lots, one can build shops of numerous types and restaurants which sims can visit by calling the Old Town trolley to take them there."
