Actually nice game with unfortunately too small extent

As a Star Wars fan, I was thrilled at the beginning ...
The game shines with a pretty good graphics, a well-designed control and by a large number of playable characters.
But after a few hours I realized how it was getting boring. The game is limited to the Game Modes "galaxy conquest", "challenge" and "rapid response", said the former represents the actual campaign. In it you have to choose one of 4 big Partein (Trade Federation, empire, etc.) It is then systematically all the planets of a galaxy by conquering a flag points. In addition, there is room fights when two ships enemies meet.
This may sound good at first, but quickly becomes tiring, as in each of the 4 campaigns always the same galaxy is used. When rapid response to fight on a preselected planet against same opponents and always at the very few available "challenges" you have to turn a number of enemies in a given time.
To my great regret, there is no campaign, in which you can replay such as on the PC film history ... Therefore, the quite considerable price is by no means justified because the latest after 2 weeks goes by the game.
My conclusion:
An actual multiplayer game that is so heavily compressed in the implementation of the PSP that it in no way justifies the considerable prize
