My brother had the floppy version for his 386, but it ran so poorly, I never got to play it. Finally, after 20+ years, I get to play this gem...and a gem it is. The controls are well thought out - I highly recommend you read the manual before attempting to play. The voice acting of the TOS cast is an awesome addition to this CD-ROM version. The graphics are obviously dated, but who cares. The episodic story lines follow the logic of the TOS episodes. This allows you to fully immerse yourself into the game. If you approach this as an upgrade to the pen and paper or text only games, you will have an awesome experience. Runs great on Windows 10 with no issues.
