Personally it would be Republic Commando - the books were good too, but I just want a sequel!
Star Wars: Rebellion by a long shot. And that’s saying something considering how much I loved Jedi Academy and X-Wing vs TIE.
Having characters run missions that shaped the course of the Galaxy really helped the game write its own stories in the Star Wars universe. Things could happen like Chewie becoming force sensitive, getting trained by Luke, and then Chewie could lead a mission to blow up a Death Star!
The constant cat and mouse game between the Rebels and the Empire was exciting. The game has kind of been reimplemented in a board game by the same name by Fantasy Flight Games. The board game is good, but there’s still magic about the original that I haven’t seen replicated anywhere else.
Rebellion was one of my first strategy games and I absolutely loved following the careers of all the characters I read about in the books. It’s what built the foundation of my love for grand strategy games like Stellaris.
KOTOR 1+2 and battle front 2.
Oh I can’t forget about the GOAT empire at war.
Jedi Academy has always been my favorite, love the lightsaber combat in that one
Dark Forces 2: Jedi Knight
Easy. X-wing vs Tie Fighter. Had so much fun with those games on the PC back then.
I would go further back and say the original X-Wing and TIE fighter 1993-1994
