I started playing “Power Planets” online.
If you have not heard of it; it is a game sponsored by Shell and created/hosted by “The Science Channel”.
It is very enjoyable; you can either reap the world for points and money, or you can save the people from pollution over load.
Over all I like the game so I recommend checking it out.
It can connect with facebook and play as a facebook game.
If you start a game on the science channel website, it will transfer over to Facebook; just make sure you sign in using Facebook and not create a new account.
