Anakin Skywalker is sad as he watches the twin suns of Tatooine set. He wants nothing more than to leave this dustbowl of a planet, to join the Jedi, free the slaves, and pilot fast ships. One day he'll find the slave chip in his body and all the other slaves will cheer as he flies farther and farther away. And someday he'll have a family, and they'll live exciting lives on big planets like Coruscant and never be oppressed by anyone.
Luke Skywalker is resentful as he watches the twin suns of Tatooine set. He wants nothing more than to leave this dustbowl of a planet, to fly through space having unimaginable, exciting adventures. He'll rescue maidens like the one in the Artoo's transmission and save the universe from the oppressive Empire that rules their lives. And someday he'll find out what his real father was like – he bets he was a handsome, exciting and brave man who grew up living a life of luxury, never having to work on moisture farms or fix old droids.
Yes, someday he'll get off this planet. And who knows what he'll find after that?
