The PSP version is way better the PS2. The PS2 has the exact same storyline as the PSP, and thats about all it has. The PSP has exclusive modes, such as Force duels, Order 66, Historic Missions, Multiplayer, etc. The PS2 has none of that so after the story is finished, you might as well chuck the PS2 version. Not the case with the PSP version. And also, the PSP version graphics are right up there with Wipeout at God of War.
