Okay first of all, now my girlfriend bought me kenshi on Steam a few days ago. LOVE IT! It's so addictive, great game, I'm having heaps of fun with it even in it's current state. I've had the game for only 4 days and already I have racked up 23 hours of play on steam. With my busy lifestyle that is a lot for me. So good job so far! This game has soooo much potential, and I look forward to seeing it grow into the final product.
One gripe with the accuracy of the way characters wear their swords though. I hope this doesn't come off as too nitpicky, but given the game has something of a realistic approach to the way characters fight, and a clear nod to samurai history, I thought I should point something out.
Samurai did not wear katana on their back, unless it was a nodachi for non-combat purposes and just for display, a foot samurai, unless wielding a spear or bow, wore their katana on their left hip, tied in an obi knot with their wakizashi as a backup. I know this because I am a Japanese traditional culture enthusiast (especially when it comes to the samurai), sword collector, and I am a passionate practitioner of Kendo (the martial art which traditionally accompanies the katana, the way the samurai trained to fight) and iado (the art of drawing the katana)
In fact, I don't think there is any documented case of any warrior culture wearing swords on their backs, unless for transport and not for combat purposes. Wealthy samurai, or even simply wealthy nobles in Japan were speculated to have worn nodachi on their backs, not for fighting purposes, but as a display of status and wealth.
In fact, drawing a sword from behind is incredibly difficult and impractical when it's simply much easier to wear and draw a sword from the hip.
I know this is a fantasy game. And while personally, I think wearing/drawing swords from behind in fantasy just looks silly, I understand a lot of people think it looks really cool, and that's okay too.
But I see this game going for some degree of accuracy in the way it portrays swordplay. So I feel that accuracy could be improved heaps by simply having characters wear their swords at their hips (especially the katana and wakizashi)
Notice here, an actual photo of a samurai, he is not wearing his swords on his back. His katana, wakizashi, and tanto are all on his waist on the left side.

Anyone who doubts me when I say drawing a sword from the back is impractical and ineffective, I refer you to Skallagrim's videos on youtube, particularly the one where he demonstrates that drawing a sword from behind is not only impossible in some cases, but ineffective and even downright dangerous in cases where it is 'technically' possible.http://www.youtube.com/watch?v=AYiXEPHLeUY
I hope this doesn't sound like whinging, because I understand this is a minor point to many, but to myself, and many of my friends who I've recommended this game to who are fellow sword enthusiasts and practitioners of sword-based martial arts such as myself, seeing characters wear swords is like having an itch you just can't scratch. It's just a frustrating little detail.
Kenshi is a great game and I'm gonna be playing this game for a long long time, whether or not the swords are worn correctly. Like I said, the game is a fantasy game, so anything is possible, but a little believablility in the finer details can take fantasy a long way.
