So many
Dark Forces is a classic. It is a FPS and the first two have real multi-level (multiple floors) on a map, jumping and crouching too. Jedi Knight: Dark Forces II is also a very good game. The former has a NightDive re-release recently.
Everyone raves about the Knights of Old Republic duology, it is one of the games that got BioWare's name on the map.
The classic X-Wing game has a good story, but TIE Fighter's story is amazing. And then, of course, there's X-Wing VS Tie Fighter. These games were when space fighting sims were big, like Wing Commander. Basically the OG version of the Star Wars Squadrons we have recently.
Star Wars Racer is a fun racing game, highly recommended if you enjoy WipeOut and/or Episode I
Star Wars Bounty Hunter is a Jango Fett game. It has some jank, like Republic Commando that is a squadron-based game, but it is great fun. Shadow of the Empire is also one of those "too much ambition ends in jank" ones.
Lego Star Wars - The Complete Saga is also a fun game to play and enjoy your time. It is funny, laid-back and the co-op is always a good laugh.
And a huge shoutout to the
Star Wars Phantom Menace PSx game. That game had no right to be a fun adaptation.
Revenge of the Sith on the GBA is a nice beat'em up.
For the RTS crowd, Empire at War, Galactic Battleground, and Rebellion exist. I did play Rebellion; it was certainly very complex. I did hear good things from both Empire at War and Galactic Battleground, so it is a matter of looking at videos or screenshots and deciding which one you might jive better
My personal picks that I would replay any time? Dark Forces, KOTOR, Lego Star Wars, Phantom Menace and Racer in no specific order.
