[Star Wars] What is the canon limitation of the force (if any)?

I consider myself pretty knowledgeable about Star Wars, but I just thought of this. There's such a huge contrast from the movies to the games/comics/books.

I mean, Starkiller pulls a Star Destroyer out of the sky in the Force Unleashed, but in Episode IV it's a HUGE deal that Yoda is able to pull an X-Wing from the swamp. And if Starkiller is SO powerful, why didn't Vader or the Emperor demonstrate some of that power level in the movies?

Remember, the Emperor was basically minorly mindcontrolling most of the Empire simultaneously, a significant portion of Vader's efforts were dedicated to just keeping himself in fighting form (Shadows of the Empire deals with him trying to heal himself further, and lacking the focus), and Yoda was near death while on Dagoba, and near a strong locus of dark side power.

Theoretically, there *is* no upper limit on what the force can accomplish. Raw power isn't the only application, either - time travel has been accomplished, and the Aang-Tii monks use the force to teleport capital ships through space instead of using conventional hyperdrives. That said, individual force sensitives certainly have limits on what they are personally capable of. Focus, willpower, talent, need...
