This is another version of the 1971 Star Trek game. This adds a lot more visualisation, a larger galaxy and more types of areas to encounter.
The Enterprise and Klingons now look like ships, and the game displays a list of actions each time so you don’t have to jot them down separately. The galaxy is now much bigger, with quadrants in three dimensions. Navigation has been altered a lot. You can choose between impulse (moving within a sector) and warp (moving to different sectors). Within a sector, the speed determines how many squares you move. For warping, you enter the coordinates of the system you want to go to and the speed (which determines how many stardates pass). You also get a really nice animation.

You also see torpedo paths animated out, making it clearer what is happening in battles. Another significant change is how damage works, as you can repair systems without navigating to a starbase, which is useful when sensors are completely down and you’re flying blind.
Overall, this is a really nice version of Star Trek.

I played a low-res version of this game on a Commodore PET back in the early 80’s. That triggered my interest in learning basic, and was the catalyst to my career as a developer. Oh the memories!
Star Trek 3.5 was a favorite game of mine as a kid. It was written in BASIC and was an early experience in me trying to understand code someone else wrote. I made some mostly cosmetic mods to it but it was still exciting to me. It too me a while to find and repurchase this copy a few years ago.
I played the crap out of the DOS port. My first favorite space game.
EGATrek!
Right! I couldn’t remember the name. I probably downloaded it from a BBS.
Yup!
A favorite from my childhood! It was written in BASIC so I went in and changed some of the graphics, colors & wording. My parents sold our Atari 8-bit stuff in the 1990s but I repurchased a copy several years ago to have in my collection.
