You will start out with Princess Leia and Captain Antilles in the Mos Eisley Cantina.
You'll see three Episode doors.
When you are just starting out, Episodes V and VI will be unavailable.
In the Episode IV part of the cantina, there will be 1 chapter, secret plans, available.
When you beat this level the next chapter will open, but Episodes V and VI will open as well.
LEGO studs are the currency of the game. The table for them is:
A blue stud is 1000, a yellow stud is 100, and a silver stud is 10.
In the center of the cantina is a bar where you can buy extras and characters.
If you get enough studs in any level, you can get True Jedi status,which gives you a gold brick.
There are Minikits hidden in each level. When you complete a minikit you get a lot of studs!!
In each level, there will be a set number of studs. When you get this amount or over, you get true Jedi status. Even if you go back down to 0 studs, you will still retain true jedi.
