I don't know how much my comment can offer anything, but I just want to say that this is the first time in trying out this mod (unfortunately I never tried the regular M&B version of this, and I lost my CD for it so I can't install it on my newer computer), but I just played this after clicking a link to this page in someone's signature.
I have to say, this mod is quite a lot of fun, and while I don't know a whole lot about Rus history, I've enjoyed playing as the Rus in Vikingr, and in this mod they are excellent as well. I also have to say that out of all the mods I've played for Warband (and I've played quite a lot), this one in my opinion as a single player mod is quite simply amazing; with that epic starting battle I had as a Rus warrior against the mongols, to going into a city only to find out I actually have to walk around and search for shops. It's really something else. And in regards to combat, while I've never had the same sort of feeling as I've had in Vikingr (compared to any other mod), with that raw visceral feeling, but this one comes really close to it, and for that I tip my hat to you all.
Here's hoping to further releases and refinement, I'll definitely be playing this for quite some time I think.
