Star wars game for original xbox?

I remember years ago playing a star wars game that i loved on the original xbox, you could create a fully customizable jedi to play with and i believe there was also a really cool multiplayer mode. I forget which one, i think it might have been jedi academy, but im not sure can anybody help me? also don't tell me to get with the times and get a 360 because i have a 360 and ps3, im just feeling a little bored and nostalgic so i want to play this game really bad, but before i can buy it i have to know which game i played years ago.
