End Goal's of a Strategy Game

Let’s talk strategy. I’ve played a few strategy games before, and plan on making one myself. The point of this topic is to generate unique and memorable end goals for a strategy game.

While I would rather avoid ideas such as world domination, I won’t stop it from appearing, or anything similar to it.

Currently, I have one Idea, that being to reach the edge of the solar system.

Important Note: Any ideas listed in this topic are open for anyone to use.
