Right! Freespace 2 was great and is still being worked on by a dedicated community. Here's a reddit thread with a review and more info on it: https://www.reddit.com/r/Games/comments/9h30rn/why_you_shoul...
Try out the knossos [0] front end to install the FreeSpace Open mods. 4k support, up-ressed textures and one of the best single player campaigns ever! And there's a bunch of user created campaigns that rival AAA games [1][2]

[Edit: you do need the commercial Freespace release to get the most of the mods. Get it from Good Old Games]
My father and I were huge fans of the Descent series and, naturally, took up FreeSpace when it came out. Out of most of the games I've played, FreeSpace has always had a unique draw to it.
If anyone happens to be reading this thread I definitely recommend picking it up on Good old Games[0] if you feel that you have the time to spare. It's best played with a joystick and is very immersive.
