I used to think Starwars was awesome, but around the time that Episode 1 launched, it turned to shit. The games stopped being cool, the new movies were lack luster, and Lucas started milking the name of the franchise more than the actual content. Games like Jedi Knight were only "star wars" in name. The game had little to do with anything we had seen in the movies at that point, while the game was expanding on the universe itself.
Now we're stuck with games like The Force Unleashed, and it's lightsabers, super god-like force powers, and Darth Vader, all to poorly fill in holes in the main story arc that no one needed filled.
Star Trek on the other hand is still a masterpiece. I'm ignoring the later 2 series, but TOS through DS9 are great stories with great characters. Characters who will walk you through what it means to be human, while exploring a galaxy that never really changes, despite the advances in culture and technology.
EDIT:
Just powerful scenes like this one:
Out of context it might be a bit confusing, but the Cardassian is trying to break Picard's will. Getting him to lie about something he knows is incorrect was one of those things (insisting that there were 5 lights, when there clearly were 4). He was being even more of a bastard in this scene, because he knew that Picard was free to go. He just wanted to stab at him once more for his stubbornness.
