Yukari, I used to run Twilight 2000, I remember it fondly. I think I did a terrible job, I was one of those GMs that stymied players and killed them off with no mercy or respite. I wonder now why my players kept coming back... In my defense the first game I ever GM'd was Paranoia where that kind of behavior was encouraged.
I've played every edition of DnD at one time or other, Cyberpunk 2020, RIFTS, Mythus, Rogue Trader (and Deathwatch), and on and on.
cynthialee and Emmaline, I've looked at (and never tried, so I can't make promises) Roll20. It looks like it can do the job well enough that a Pen and Paper game could be played online, it might solve the logistics issue?
I would be interested in joining a game if one were to happen...
