This is one of the greatest Star Wars games in the whole entire world. This game introduced me to Star Wars back in 2002 as a child and my love of star wars began with this game (not with the movies).
12 years on and this game is still brilliant, it has one of the greatest single-player stories I have ever encountered with Star Wars games (and one of the most fun as well). It also has cool cinematics! And the voice of Billy Dee Williams (Lando from the movies)!
It also has brilliant multi-player, the game types are fun, the maps are cool and the gameplay is excellent. Despite whether you are playing with bots, or other humans multi-player will still be fun.
Also, when you wield your lightsaber and stick your lightsaber into the wall (or another person), orange lightsaber marks will form. This is one of the only Star Wars games I know to actually have this feature. Quite cool, especially for a 12 year old game. :)
