Holy Smokes, Combat Zone!
It was the first generic wargame I tried to get into almost 20 years ago.
I even had an article in the Combat Zone Chronicles:

Never did manage to play more than a game or two, but it was the gateway into the world of generic wargames and the post apocalyptic Mark-Coppleston-Sculpted, originally-Grenadier "Future Warriors" figures that EM4 still sells are still some of my favorite minis.
Nice Blast from the Past!
