Play Chapter 1 of Episode IV: A New Hope. Destroy all of the little panels that a Force user can open. You can also go through the Bounty Hunter or Stormtrooper doors and use the Force on all of the little panels on the wall. Another way is to go through the door that can only be opened with a Sith (for example, as Darth Vader). Then, use the 2x Score Multiplier to your advantage.
Play as a Bounty Hunter (Boba Fett, 4-LOM, Greedo, etc.) at the Mos Eisley Cantina. Enter any mission. Character bonuses are recommended. Immediately when the mission loads, pause game play and return to the cantina. Once there, go to the outskirts of the cantina and destroy every trash can, ship piece, and platinum object you see with your bounty hunter's blaster and/or thermal detonators. Collect every stud possible. After you have destroyed everything, you can repeat the process as many times as desired. This is a quick and easy way to get at least 20,000 to 30,000 studs each time.
Go to the Mos Eisley Spaceport in Episode IV: A New Hope. Walk up the stairs on the right. keep killing yourself. When you collect the studs you will get twice as much back.
Go to a chapter that you have already completed. Do it again in Free Play mode The Secret Plans (Episode IV, Chapter I) with Darth Maul as your main character is recommended, because he can open doors that Ben Kenobi cannot.
This allows you to access areas full of wealth, minikits, etc. If you scour this stage from top to bottom you can get over 130,000 studs. Repeat this as desired. Destroying containers of any sort and opening drawers using the Force will dramatically add to your stud count.
