The GBA Version of LEGO Star Wars II was released alongside the other versions on 11th September, 2006. The GBA Version is very similar to the original game on GBA. It's played from a top down perspective and there are less levels than the Console Counterpart.
Unlike LEGO Star Wars however, the GBA Version of II has a hub world (in this case, Mos Eisley Cantina), with the levels being accessed from there. There are also more characters to play as (though still less than the Console Version). True Jedi Stud Meters are in the game, and the usual 10 canisters per stage is also seen here. Overall, the GBA Version of LEGO Star Wars II is both similar to it's console counterpart, while also being very different at the same time.
