SMAC had so many awesome features it would make the heads of fans of lesser games EXPLODE!!!! And I've only played a DEMO!!!! It had everything: blind reaserch, war crimes, cutom units, swarms of brain-eating alien worms, mysterious alien fungus, An evil ultra-capitalist black guy (I wiped him off the face of the planet), and MUCH MUCH MORE!!!!! You could equip Units with nerve gas and use them to slaughter enemy citizens! You could "nerve staple" (what does that do anyway?) Unhappy people! You could do almost ANYTHING!!!! And again, I've only played a demo.
