I bought Sheep today, which is a PC game. "According to the game sheep are a highly evolved alien life form which was sent to Earth millions of years ago to observe the planet. Unfortunately as the years ticked on the sheep forgot their mission and became the docile animals that we know. Those who left them on Earth have returned and it's up to you to guide the sheep across seven "worlds" to their final destination so they can head back to their home planet." It's kinda like the old Lemmings or Gruntz. I like it.
