I've got this idea for a game

I've always wanted to build a game that starts with a blank white page that eventually turns into this multi-faceted, complex game system. I know Spore is kinda like that; single-cell organisms that you guide into a civilization, but I'd like it to be more open-ended. Less logic-driven.

How do you logically program something to have no built-in logic? I really don't know. I suppose it would start with a very basic type of "if...then" reasoning, which it could eventually build upon. Or maybe even an automatic response to stimuli which it then evolves into a type of reasoning based on input.

Like you start it all by moving your mouse in a certain direction, and that draws an object on the screen. And that object is all you have or, rather, that object is all you are. And it slowly transforms and learns and replicates and turns into all kinds of cool crap you can interact with.

Maybe you don't have a particular character, you just kind of Populous-style interact with the environment. I don't know, I don't have it all worked out (obviously) but I think there's something to it.
