When you build your lightsaber in the Knight storyline. That was probably my favorite moment in the game. It still gives me chills, it's just such a magical moment. Basically every moment as the Smuggler. Just being the biggest, most sarcastic, and flirty playboy that he is is just so damn fun. The first trip to Coruscant. The planet just felt so massive, and after hearing about it and seeing brief moments of not on the movies, you FINALLY get see it firsthand and explore it.
