devil kings is a musou game, it’s the heavily localised version of the first sengoku basara game, plus it adds some weird mechanic where you have to do charge attacks to weaken enemies before doing your regular combos on them or else your meter won’t fill up.
if you’re looking to play every ps2 musou game, then demon chaos is actually good and has stuff to add to the concept, the oneechanbara games have boobs and gore, and buccaneer is pirate-themed
