Personally it would be Republic Commando - the books were good too, but I just want a sequel!
Dark Forces 2: Jedi Knight
This one for me. Such a solid, classic shooter. Only problem was the first level or so was obnoxiously hard, at least for 10 year old me.
For me it was how scary the game got a few levels in. The probe droids with the deserted homes where you get ambushed, oof. Had to have my dad play through those levels while I watched, but he didn’t know where to go so I eventually had to gather the courage to do it myself!
KOTOR 1+2 and battle front 2.
Oh I can’t forget about the GOAT empire at war.
Easy. X-wing vs Tie Fighter. Had so much fun with those games on the PC back then.
Definitely Jedi Knight II: Jedi Outcast
X-Wing (1993). I’m old. It is still one of the best games I’ve ever played.
I spent so many hours on that game as a kid. I had a Sidewinder joystick on my Acer i386 running Windows 3.11.
Years later I played X-wing: Alliance but it just wasn’t the same.
Galaxies. RIP
I liked the Rogue Squadron games…and obviously Episode I: Racer. Played the hell out of Racer.
I’ve always loved Galactic Battlegrounds because RTS are fun. Rebellion is another great one that another commenter mentioned. I was also a fan of Jedi Knight and Jedi Academy and replaced them on switch a year or two back.
Kotor, but mostly the second one. With the restored content it’s so much better than anything else that it feels unfair.
