While I love TNG (even though the cast can’t shut up) and that was the first Star Trek I was familiar with since I was 6 and a fan of reading rainbow when it came out I would say that the original series is my favorite (can happily watch Trek through Enterprise). My dad watched Original Series reruns since as long as I can remember.
The sendoff for the original crew always gets to to me and it just contrast that with writers today who live to crap on or deconstruct the works of better writers. I saw they are making a new blade runner with a delusional man, Disney is making a new Neverending Story, and Netflix is butchering… I mean remaking the Chronicles of Narnia.
One good thing about Star Trek is that I have a lot of books to read. I was at a convention once and a guy had a bunch of Star Trek books for a quarter a piece so I left with a bunch.
if you can track down a copy, star trek: shattered universe was a great, if hard, game. Basically, the excelsior ends up in the mirror universe and has to fly halfway across the alpha quadrant to get home.
The twist is that they're in the bodies of their mirror universe doppelgangers, and the ship has star fighters instead of shuttlecraft.
not necessarily canon, but a fun game, and you get to see what kind of captain sulu might have been.
