I'd just like to say a few things about the current realms. While the competition in Western Europe looks to be fierce and fun, in the east, Poland is unopposed. There is no Hungary, there is no Kiev, no Russian power AT ALL. Furthermore, the Scandinavian powers will be too busy fighting each other to stop me from moving into Russia. Just so all of you know, I am a competitive player, I thrive on conflict, I love to rip through countries like a machete through cardboard. No humans to my east won't stop me from expanding east like a fiend, but it will make it a considerably less fun game for everyone as nobody wants to see a Poland unopposed.
EDIT: Furthermore, I'd like to strongly, strongly encourage AAR-writing in this game. While, unfortunately, AARs in March Through Time fizzled, I believe that writing AARs in a game spanning this much time is crucial to create an atmosphere of being able to change history. One can look back at AARs and either remember his nation's time of glory or see how much better he has made his nation. In 1802 when Polish general Tadeusz Kociuszko leads a cavalry charge through the Russian line at Smolensk and kills the Russian usurper to the throne (thereby ending the Russian rebellion and restoring Polish reign over all lands north of the Balkans from Hessen to Siberia), I want to be able to remember when Poland was on the ropes, being pressed on all sides by the Danes, the Germans, the Bohemians, the Baltic Pagans, and the Russians, that in the end, it was Poland that triumphed.
Now, to encourage AARs, Lurken and I have come up with the following reward: either +200 prestige or -.2 BB penalty for writing an AAR. Any other ideas?
