The graphics look really good. Personally I'm not really for the whole "folded a gorillion times katana", though. Historically speaking, the katana was not functionally 'better' than a European longsword. The reason weapons in feudal Japan took so much effort to make was largely due to poor ore quality that required a lot of purification, and also its scarcity (hence wooden armour). The curvature of the blade allowed for a better cut with a swing, but the longsword's sheer length and weight largely made up for the lack of a curved cutting edge. A straight blade also allows for more controlled parries than a curved blade, and this is evident in medieval swordplay tactics. Despite common belief, a katana was perfectly capable of effective stabs; hell, I've seen modern videos of it punching through steel plate. Of course, the European longsword was also fully capable of piercing attacks and typically at a greater length.
To sum things up the katana wasn't a super amazing sword, it had its strengths and weaknesses like many other melee combat weapons.
