I love STBC aka Bridge Commander. I sure have it nodded out pretty heavily but primarily having the Galaxy charts and Kobayashi Maru mod gives it a lot of life.
You can make your own ships, have fun with face replacements and voices, pack it with real solar systems and all kinds of customisations. It’s a lot of fun.
Fir a flashback now and then, I also play an old Star Trek game from SNES. Budget as hell but good for a laugh.
