Stress reliever
This is a great game. It offers many different things to do with your little "buddy", though I really doubt many people would try to take care of him. The physics are great, especially for a game of this type. It offers a lot of ways to tweak the game, and even gives you access to the scripting engine, for a price. This allows for a lot of things to be done.
My only problem is, the selection of things to do can become quite limited if you play it too long. However, this isn't the type of game someone will play for hours straight. I definitely recommend it!
