Title. Civs may be never seen before but also even ones already present, or even mainstays. Also: your reasoning why, calm and reasonable. Bonus points if the civiliations you have a grudge against are not obscure but somewhat popular on these forums, as this may lead to interesting debates Also, please keep far from injecting modern political views here. Me: Inuits, Harappa Harappa - I was supporter of this cov until I learned its language is (one of very few) completely undecyphered, so we know nothing of Indus Valley civ beyond archeological remains. No leader names, biographies, nothing. Inuits - no candidate for leader, no cities, no state structures - easy points. My biggest problem with them is however how people dream of Inuits because they'd populate snow areas. Uhm, Inuits are still humands and they don't magically grow yield out of barren wastelands, they adaptation means "they can survive in those awful conditions" but "survive" doesn't mean "building cities"... Even them cannot do that. Some parts of the planet are simply unsuitable for urbanization.
