This game is a bit addictive and it's kinda sad whenever humanity goes extinct. But such a warm fuzzy feeling when the colonists end up weird but happy. http://philome.la/johnayliff/seedship/play
Seedship

An AI ship full of frozen colonists must find the best planet to be the new home of the human race.

I ended up being dinged when my colonists ended up reverting to a neolithic culture on floating platforms. But their society was built on equality and they had awesome animal pets. Probably more sustainable than whatever doomed earth.

I lost most of my colonists to earthquakes and poisounous plants, but I had quite a bit of scientific knowledge amd the planet was so rich in ressources they entered post singularity and built themselves hanging cities in the huge trees.

Unfortunately the small population and dangerous conditions drove them towards a dystopian police state... but hey, they're alive
