I played this on the PS2 and it's s fantastic experience.
Interestingly, the PAL version (and probably the Japanese version, too) has content that wasn't in the NA version. There's an extra puzzle, a semi-hidden alternative "funny/happy" coda after the main ending if you play through a second time, and some extra in-game options that are unlocked after you finish the game for the first time, including understandable subtitles for ALL characters, even ones that are normally speaking an unknown language. I'm not sure if the hidden weapon you can get in the middle of the game becomes a light saber on the second playthrough in the NA version as it does in the PAL version, but it may.
This was before video streaming sites, so there were many arguments on forums about how these things are in the game, no they aren't you trolls, yes they are here's a picture, that's obviously fake... and so on. It was interesting that once people figured out that the NA and PAL versions were different, there was a vocal core of NA players still insisting that it was all fake for quite a long time afterward.
