In my opinion, two series and a one hit wonder need a comeback;
1; Jedi Knight series: The best series in my opinion (I still own Jedi Academy) I think Platinum Games would be good to pick up where Raven studios left off due to their familiarity with melee combat, that was the staple of the series; The Lightsaber, yes you had OTT force powers (If you rank them up quickly) but the combat was astounding, it felt like you were actually dueling a Sith and one wrong swing could get you killed, I want this back the most.
2; Battlefront series: predictable I know, but to the average Star Wars game fanatic if you asked of them: What was your favourite Star Wars game? They will almost always shout: Battlefront! The game where you could be most character (Hunt mode) Be a Jedi/Sith after accumulaing enough points and SPAAAAAAAAAAACE combat that was awesome in the hands of even the most novice of pilots, I will admit, going back to BF2 now the AI is laughable but think about how advances have come along now? I look forward with great anticipation.
3; Republic Commando: By far the best FPS of the Star Wars game list, the squad command's were good, the AI was half decent and the threat was real, you made a wrong call you would get that squad member knocked down, if you were knocked down, you could ask your squad for help (Something Gears of War 1 forgot to add), varied enemies as you went to different worlds and a cliffhanger ending that begs a sequel, Disney; this is the game you are looking for.
Honorable mentions:Rogue Squadron: A great flight sim that had varied objectives and created spin offs from the good premise (remember Battle for Naboo?).
Star Wars Demolition: Vehicular mayhem that pitted you against multiple opponents, good combat, nice locations but a little bit clunky and cash in 'vehicles' like Jabba's Rancor.
Star Wars Bounty Hunter; A game where you played as Jango Fett, similar to 1313 it took place on Coruscant where you were hunting a Dark Jedi called Komari Vosa, it had all of Jango's toolsand felt like a fun, if short game.
