It was a game that I played around 1990-1993 (IIRC). It was a game where you had a top-down star map on the right, and you flew around to different planets, and fought Klingons. You could choose your “rank” as a means of levels of difficulty, and if you screwed up too much, you were relieved of your command. You had to power up photon torpedos, shields, etc. I think you flew by dragging a line from your position to another spot on the top-down map
It is kind of like Begin, but the graphics were much, much better and you could use a mouse… I can’t see any screenshots of Begin 2, but it seems even more advanced than that. May have been called VGA trek or something? Any thoughts?
