Halo there,
just to add to what Patric has posted,
snowball.ru is our sister company that is focused on publishing in Russia while
Snowball Interactive is the development studio. We used to be all together both in corporate and in actual but since this winter we're running the divisions as separate companies with focus on different things. So S.I. is the one working on Crusader Kings, while snowball.ru will publish the Russian version here (and if they do a less-than-perfect job, we'll maim them

.
Re: our track history, the biggest thing we've done (and not through, actually) is
www.fatherdale.com, the medieval RPG/adventure.
Re: team, to add to Patric (again

the Russian part is like that:
Boris "Boreal" Puzitski (Designer)
Alex Zdorov (Engineering/Design Consaltant)
Vitaly Klimov (Engineering Consultant)
Sergei Rozhkov (Programmer)
Vladimir Bulatov (Research Consultant)
plus me as Theo's co-producer and Mike Kolbasnikov as Game Artist plus maybe Masha Zhalnina also as Game Artist later on.
A fact worth mentioning is that Vladimir works in Dept. of Cartography at the State Historical Museum here, the chief authority on the Russian history (you should see their new Exhibit Halls on Red Square!!

. Another fact is that Boris is probably the best-ever Russian player in EU, he's been a leader of the Russian forum of the series for a long time and knows it in and out. Add here an utterly constructive mind, and you have a killer designer
