I forget if it was Rogue Squadron or Shadows of the Empire that had a mode with MST3k style commentary, including silhouettes, could be added to the game on subsequent playthroughs. Me? I'll be buying Rebellion, which was flawed but still fun.
Actually, unless they also did it for Rogue Squadron, the MST3K mode is originally from Rebel Assault II. Still have it, but it's been awhile since I've seen it. One of the best Easter Eggs in game history. At least in RA2's mode, they disable the voice acting and put up silly subtitles, while C3P0, Darth Vader, and R2-D2 sit in front of the action. Through EVERY...SINGLE...CUTSCENE. And it's all hilarious.
"Look, sir! I have new boots!"
*Radio static* "Did you..." *static* "Hear the one..." *static* "Agnosic, Dyslexic Insomniac?" *static*
"Ok, son, listen to me. I'm the old guy."
Very few people can make fun of their own product. Even fewer can make it more fun than the original game.
EDIT: In fact, the code to enable it is OVRES. Think about it.
