-In Episode IV: Chapter 1: 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.
-Note: Auto save must not be enabled for this trick to work. Find all Studs possible at Mos Eisley. Then, save the game, press Start, select "Quit Game", then "Yes". Note: You must go to the start menu and quit the game. Turn off the system then turn it back on. Load the game and you will keep the Studs you had and can go to the places that you got your Studs the first time and get them again. Repeat this as many time as desired.
-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 the game 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 all Studs possible. Repeat this 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 a chapter that you have already completed and play it again in Free Play mode. The Secret Plans (Episode IV: Chapter 1) 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 much desired. Note - Destroying containers of any sort and opening drawers using the Force will dramatically add to your Stud count.
-When you go outside, get a bounty hunter and blow up everything. You will get 30,000 Studs each time. Repeat as desired.
-Play Episode IV: Chapter 3 in Free Play mode. Make sure you have a Sith character and break everything.
