This is the edition of Twilight: 2000 that really grabbed me. I bought it based on the adds in Dragon, and I loved it. I got to play very little of it, but I own most of the supplements for it. They're amazing. With the right group - a wargamer-heavy group, especially - it would have been amazing. Some of the design decisions - such as the really long equipping-the-group part of character generation, the roll-well-or-die aspect of determining your initiative score, and the whole "bullets" vs. "shots" issue ("This game is bullshit, a revolver doesn't only have 2 shots!") . . . all conspired to not let me run it in high school.
But I still love the game for all of the other things I got out of it. And it's still attractive today. Check out this post:
