From Single Cell to Galactic God, evolve your creature in a universe of your own creations.
This was the first version of Spore, whitch I think was 100x better than the new one.
Some Features that are not in the new version:
Features of Galacic Adventures
Advanced Editors and Creatures
Blood and ragdoll
Parts for Creatures (Brains and other stuff)
Creatures whitch live like birds
Free City building (you can build roads, have a custom space for building and more differen Structures
and many other things whitch are missing...
