I'm a long-time gamer and I bought 1e of Twilight 2000 back in the day. I never had much of a chance to play it, but this is one of those games that I have always admired from a distance. Having been a teenager during the 1980's, the Cold War setting makes me feel young again.
Anyway, the biggest issue I've had with previous editions of Twilight 2000 is combat. Getting shot is normally a bad thing. I don't like games where getting shot means you just check off a few hit points, slap a band-aid on your wound and keep playing as if you only suffered a mosquito bite. Combat should be something you want to avoid unless you are very, very sure you're going to win the fight without getting hurt. (And even then...)
So what do we know about combat in this new version? That's what might determine how excited I get about this. I've never joined a kickstarter before, and I'm sorely tempted with this one!
