In the world of fantasy gaming, realistic weapon proportions take a backseat to aesthetics. Think about how cool (yet impractical) all of the Final Fantasy weapons are.
I appreciate the edit, FishyFish136. I agree that some games do go overboard with weapons that are too large. I guess we'll just have to leave it up to Dasius to see how fantasy or realistic he'd prefer his game to be.
Aside from the silliness. It is a fantasy game so technically anything (almost) goes. You might be right on the thickness of the blade. None of these weapon parts are final. So i will do another review of each part when I get the chance.
