It's everything we love about Star Wars
I consider Jedi Outcast one of the best narrative Star Wars games ever. It's a simple and straightforward story, driven by the most classic of action hero motivations: revenge. It's a fine line to walk for our Jedi protagonist, Kyle Katarn. But he's no Luke Skywalker. From blasters, grenades, mines and more, no weapon goes left unused by Katarn in his quest for answers. And yes, that includes lightsabers.
In fact, the Jedi Knight series still possesses the best lightsaber combat to date. Every swing, every thrust has the potential to be deadly, whether it's your lightsaber or your enemy's. No florescent batons here: swings cut through enemies neatly and quickly, as they should. Enable the dismemberment option for increased pandemonium.
The greatest con might be the series' age. The visuals definitely diminished with time. But see if that still matters when the game hands you a lightsaber, a room full of Storm Troopers, and John William's score begins swelling.
Oh, and did I mention they got Billy Dee Williams back to voice Lando? Because they got Billy Dee back to voice Lando. Awesome.
