Hey, Paradox awesome dudes.
Your games are awesome.
Only one question, though: y u h8 rasha? Srsly, guise. Why you invent non-existant province names like "Mordvar" or "Idnakar"? Why complete randomness province-wise in Siberia? The first half-decent map of European Russia only appeared in DW. CKII isn't too accurate, as well. No other country is as messed up on the map in any of your games. What's the matter, Swedes? Old rivalry much?

Anyways, you guys are cool, and there's no doubt you'd make an even awesomer game outta EU4. But give Russia some love, for a change.
In the light of the aforementioned facts, allow me to present you a [quickly made and not very aesthetically pleasing bluprint of a] detailed and historically accurate province map of Russia (1444 starting point) that is relevant to the games' timescale. Prolly too detailed to be fully implemented, but it may be useful for future modding. The map is only about provinces and their relative size and position, *not* about borders, which could be adjusted and fine-tuned the way you deem useful, so ignore the blobness.
edit: hmm, im new to this forum, and apparently the pics on here are automatically scaled to fit the post space. can't figure how to get them properly adjusted yet.
Okay, for now, I'll just post them links, then.
