First of all, this game stars Kyle Katarn. Next slide.
No, but really, many people debate whether Kyle is a bad ass straight out of whatever Star Wars people call hell or a literary Mary Sue. Not only was he a cool character, but the games were actually really fun to play. They may seem dated by today's standards, but this game was like The Force Unleashed for the early 2000's.
Here's where the eureka moment happens. Combine the creativity of Jedi Knight II: Jedi Outcast with the fast-paced and pretty looks of The Force Unleashed and you can really give the Jedi Knight series the comeback it deserves.
In Jedi Outcast, players started off not being a Jedi and slowly learning the ways of the Force. This meant fighting with a blaster and other non-lightsaber weapons. As you progressed through the game, more force powers were achieved, giving a sense of accomplishment.
Now obviously, The Force Unleashed was a game about a fully unleashed Sith apprentice with overwhelming power from the get-go. That's fine, it's what it was. But applying the progression of Jedi Outcast to the mechanics of The Force Unleashed could be a big accomplishment. It could even be done from another angle, putting a Jedi in the driver's seat once again.
