Has anyone ever heard of this game in development called "Spore"? It looks supa-cool.
Here's the basic premis of the game: You start out as a teeny-tiny like one-celled organism. The game starts out with you avoiding being eaten by bigger organisms, and eating other organisms your size.
Eventually, you start to grow. You can get flagellae, pseudopods, or any other means of transportation you feel neccessary. Best of all, the games coders are geniuses. They made a game engine that can figure out how your species/character should move depending on the number and position of limbs and mass of the creature. It's totally cool!
Eventually, you evolve into your own race and start to build towns and buildings. You can build spaceships and fly to other planets to see what kind of races live there. You can even have dogfights in the spaceships!
To me, this game epitomizes ingenuity and creativity. I am totally physced for it.
