Not only is this an interview with SimGuruRyan, it’s also a sneak peak at the development of Horses for the Expansion.

Buttercup: I understand that horses were the most requested pet ever from Sims fans. Why Sims 3? Why didn’t you give us horses what we wanted with The Sims 2 pets?
With The Sims 3 Pets, not only did we want to include an animal that our fans have been requesting forever, but we wanted to feature a pet that could really take advantage of the vast open worlds that The Sims 3 provides. Because of their ability to explore and cover large distances in no time, as well as their special capacity for befriending other pets and Sims alike, we felt horses were a perfect choice to include in the game.
