The renaissance was a period of learning starting at roughly the late 1400s, in which europe begins a revival of roman culture and science becomes a novelty rather than a heresy. Key differences include: - No armor. Armor was given up when the earliest guns were produced, seeing as they could punch right through thick plates. - Early guns. Things like muskets and one shot pistols that take thirty seconds to reload. - A large emphasis on the sciences, arts, individualism, and pleasure (at least in the upper classes. The lower classes don't notice any change).
