no, not Will Wright, the other one.
Let's go off on a bit of a speculative tangent for a minute. And please remember (for the duration of the thread) that
I'm talking about the game, not real life and I don't want to go off on a tangent for the same question about real life.
Where did we come from?
At some point, we'll be able to put life on other planets (in fact, it's one of the clearly mentioned goals) and actually create life for other planets. We'll be able to raise life to sentience (sapience) on other planets. So, were we made by a greater species? Was our first bacteria sparked to life by an alien ship passing over our planet? And the most important question, will we meet them? How cool would that be for an end-game storyline quest and a 'welcome' to the full sandbox mode? We finally meet the species that created us, and we are now as powerful as they are, they tell us they'd been watching us for millenia. They had been monitoring us as a personal project. Perhaps they're hidden somewhere in the galaxy and we can stumble across them by accident, or find clues such as a monolith on a planet that we didn't place.
