NO.
Steampunk is fine for alot of things.... dont wanna see a feudal japan with samurais and steampunk.
Rather just have the Samurais ^-^.
Just give me a game of feudal japan, that plays like being inside one of James Clavells - shogun book series.
No need for sorcerers / supernatural elements. If it needs classes theres still tons you could make without supernatural elements.
Dont need monsters,.... enemies are just factions that all want to be shogun.
