I read that the Force Unleashed will have customizable lightsabers, like changing the hilt, power crystal, and color crystal, stuff along those lines. I want to know if the PSP has this feature.

Reason I'm asking so many TFU for PSP questions is because, well I'm getting it for PSP. Also an added question, will the costume changes in some levels be in the PSP as well?

You could go to GameSpy or some media site for games with trailers and stuff.
You can check the reviews for PSP TFU to find all your questions.
Or go to TFU FAQ on a FAQ site.;)

Ha, but seriously, if you have a choice, I wouldn't get it for psp. So far, all it has done to those select games that are released for multiple systems is ruined them. (BF2 etc.)
