'Nodachi Samurai' is a modpack that replaces the Teutonic Knight with a Samurai carrying a Nodachi ( very long type of sword ). Note, what it replaces should have been mentioned in the description.
The mod looks ok and doesn't have any bugs, as in anchors etc. work perfectly fine. The samurai also looks quite good.
My only complaint would be that doesn't look as good as ES graphics or those from another game. It does have the discernible features like the Samurai mask, his clothes, sword etc. but doesn't quite have the natural feel of ES graphics.
I know very well however that the original ES graphics were made by experts and the original models had over 20,000 polygons rendered for every unit. I would not expect that kind of work from any amateur and it is to the authors credit that he has built up a decent looking unit from scratch rather than copying/modifying a graphic from somewhere, but I can only evaluate how it ends up looking.
