I love the Pen-and-Paper RPG, and bought Twilight:2000 back in the day; and played a great deal of it. While it shows its age, it's still a great experience, and really asks for a remake - the vehicular combat was something I never could get right, so I used a HMMWV for everything, went to the adjacent field, and from there used sniper rifles, and MANPATS for the armour.
It replicates one campaign of Twilight:2000 (1st Edition). It would be great if it was re-released.
