It's good to have ambition in a game. It's what drives characters to seek adventure. The desire for more wealth, influence, and/or arcane knowledge is the reason a blacksmith's apprentice takes up a sword and leaves town, an elven boatmaker leaves the forest to see the wider world, or an innkeeper's daughter travels to a distant city to seek a wizardly mentor.
And the good thing is you can always go a step higher. Run the kingdom? There's always one next door. Run the world? Try other planes of reality. Or other worlds. Power!
Power! Unlimited power!!!!
Obi-Wan: Hey everyone. Looks like we're the last to arrive.
R2-D2: What's the news, Sally?
Yoda: I'm not a reporter, silly! They don't go down in history. I'm going to be making the news.
Obi-Wan: She's running for class captain at school.
Yoda: And then Prime Minister! I'm going to be a politician!
Padmé: Awesome! Following my lead as a Senator.
GM: Speaking of the fine art of diplomacy, Anakin is leading the 501st Legion clone troopers into the Jedi Temple...
Yoda: I could be President of the World!
Obi-Wan: Don't let me stop you.
Yoda: Just because you don't have any ambition.
Obi-Wan: She's been even more unbearable than usual this past week.
R2-D2: Good start to her career, then.
