Star Wars Jedi Knight: Dark Forces II

Star Wars Jedi Knight: Dark Forces II is a first-person shooter video game developed and published by LucasArts, released in 1997 for Microsoft Windows.

Plot
Star Wars Jedi Knight: Dark forces II follows mercenary, Kyle Katarn, as he tries to stop the murderous sith lord Jerec from discovering the Valley of the Jedi and using its power to take control of the galaxy.

Why It Rocks.

 * 1) Great plot.
 * 2) Interesting characters.
 * 3) Kyle Katarn is a badass.
 * 4) Live action cutscenes that are so cheesy they are awesome.
 * 5) A large arsenal of weapons including lightsabers, blaster rifles, and rocket launchers.
 * 6) Excellent graphics for 1997.
 * 7) Extremely fun old-school FPS gameplay.
 * 8) Fast movement speed comparible to games such as Quake and Duke Nukem 3D.
 * 9) Lots of enemy variety including monsters, imperials, and gangsters.
 * 10) Challenging, but fair gameplay.
 * 11) Varied and interesting environments.
 * 12) Decent length (6-8 hours) that encourages multiple playthroughs.
 * 13) One of the first Star Wars games to incorporate a "lightside-darkside" system that actually alters the way the game plays. Depending on your alignment, both the force powers you are given and the story change dramatically. There are even exclusive levels depending on this.
 * 14) Force powers are useful and fun to use.
 * 15) Game awards players for being either full light or full dark by giving them exclusive force powers for both.
 * 16) Lots of boss fights.
 * 17) Lots of secret areas in levels that encourage exploration.
 * 18) Some decent puzzles.

Bad Qualities

 * 1) Boss fights can be a bit basic (slash them until they die).
 * 2) The darkside storyline has far less cutscenes than the light.
 * 3) The environments can sometimes get tricky to navigate due to the size.
