What is your favourite Star Wars game?

TIE Fighter's my favorite, followed by KOTOR.

Star Wars: Republic Commando, game's still badass to this day. 
 
I DEMAND A SQUEAL LUCASARTS!!! 

JK: JA

Battlefront 2

KOTOR

TOR

Fucking Tie mother fucking fighter fucker. Accept no fucking substitutes.

5 year old necro. Nice.

I don't have a singular favorite. I like several Star Wars games.

You could argue Star Wars Galaxies was my favorite since I played it for 5 years, though.

Star Wars: Knights of the Old Republic without a doubt. Honorable mentions go to Jedi Knight 2, the trilogy on SNES (Empire being the highlight, though I played the first one more) and the Traveler's Tales Lego version of the original trilogy which blew my mind on PS2 back when it came out. So much nostalgia before nostalgia became such a thing. Too bad TT then proceeded to drive the formula into the ground. I never played any of the flight sim-ish ones.

I've had the most fun playing the Battlefront series although I will concede that they are not "the best" Star Wars games. They just seemed the most effective at making me feel like I was in an important battle.

Crap! Is it too late to change my answer to Star Wars: Super Bombad Racing???

Jedi Outcast, Rogue Leader and Knights of the Old Republic.

Gotta be Knights of the old Republic.

Dark Forces and (weirdly) Star Wars. Episode 1: The Phantom Menace are pretty good as sell.

Rogue Squadron. The 2nd one on the gamecube had my favorite Star Wars level. The battle of Endor was great.

Ctrl+F "KotOR". 25 matches.

Yup. And more than a few were for KotOR II. Good job, people.
