Permutation City Blog

A collection of religious groups settled a planet and built marvelous cites. The cities were programmed according to the scriptures and soon found that mankind was wanting. All were expelled and a thousand years they later still wander the planet looking on at the empty cities. However the cities stripped of purpose are dying.

Can't remember where I found this but it looks fun. You have to save the stars but end up destroying lots of things on Earth in an entertaining manner. There is a description on Wikipedia and some videos on YouTube. (I finally got to play it.)
