Jedi Outcast/Academy/KOTOR 1 + 2/Republic commando are all superb games. But cant say if they have aged well since i haven't played them for a long time. They were released even before 2006. Probably using source ports if available could help.
Fallen order is pretty popular, so could try it. I did not like it but maybe will give it another try in future. Had also bounced off Witcher 2 in this way and in next try i really loved it.
