8. Knights of the Old Republic: Darth Revan
https://www.youtube.com/watch?v=FFvN2y9PI3s Knights of the Old Republic will remain as one of the greatest Star Wars games ever created. Long before LucasArts was brutally murdered, they released this game. With incredible characters, great environment, and awesome story, this one became a fan favorite, and it's still a very enjoyable game to play. In it, you play as an unknown Jedi who helps the republic defeat Darth Malak's forces. However, as you play the game, you start to notice something very...odd about your character. Near the end of the game, you encounter the big revelation that you are Darth Revan. Malak's old master, and the responsible of the current state of the universe. In that moment you must make a decision, either you choose the path of the Light-Side of the force, or you join the Dark-Side, the rest of the story will depend on which choice you make. However, after a reveal like this it would be very hard to see something that would top that off.
