Star Wars: Jedi Musician.
First person. You basically are a Jedi, but before you play, you have to choose a homeworld, a race and an instrument. Sometimes you have to fight your way between two concerts with your lightsaber(s). Sometimes, in a concert, you have to fend off Force mind clouds and even fire back at the attacker using your own Force mind clouds. The level bosses vary greatly from instrument to instrument. It is easier to win a concert if you make use of the Force that if you didn't in most cases, but if you use 45% of your nominal power to perform, the opponent will also use 45% of its nominal power.
There are ten missions for each level of difficulty for an instrument. To unlock one secret level of difficulty, Nightmare, you need to beat the game at Hard level with every instrument. Same thing for Hell, but this tiem you need to beat the game with every instrument in Nightmare mode. The last two missions for each instrument will be called Coruscant I and II because of the places. The subtitles may vary.
Sample bosses for Coruscant I or II:
Alto sax: Lisa Simpson (Coruscant I), Yvan Ung (Coruscant II)
Oboe: Agen Kolar (Coruscant II)
French horn: Ki-Adi-Mundi (Coruscant II)
Baritone: Diandra Grandchamps (Coruscant II)
Flute: Darth Tami (Coruscant I), Melissa Dery (Coruscant II)
