I've really never been high on video games, I've always had a hard time finding any value in them. But Spore has certainly caught my attention.
It allows a player to control the evolution of a species from its beginnings as a unicellular organism, through development as an intelligent and social creature, to interstellar exploration as a spacefaring culture.This game ends up being a coincidentally perfect example of what creationism would look like if you were God. Hope no one gets confused ;).
Reminds me of that Halloween Simpsons episode where Lisa accidentally creates life - she watches the evolving humanoids create fire, civilization, and then futurama-like cities. Since their technology surpasses ours, they develop a shrinker ray and beam her down into their world believing she's God. Then they start asking her all the big life questions - my favorite, "Why do good things happen to bad people?"
