I know way, way more about like, 1400-1850ish than I do about the "medieval" period because more interesting stuff happened in it. It's also when the longsword/sword&buckler styles I fight in were actually in vogue. Unless you really, really love viking swords, the sword you think is cool is from this era. You get cool tactical stuff too; like, all the way up through the American Revolution a dude trained with a bow is just better than a guy with a gun in terms of actual effectiveness, but it's easier to train people on how to use guns effectively. There's way more room for serious ideological diversity among your cast of characters. Tinkers/Alchemists/Artificers make more sense thematically. The early modern period rules!
