Hey Quinn, could you share with us your ideas about the social and economic changes in 4.0 (the replacing of the barracks line of buildings, the different possibilities for developing a province, etc.)?
I believe with large enough audience you could pick us up for useful ideas.
On a separate note, it might also be a good idea to release a beta version of the changes(compatible with 3.3.4), since that would change a lot the game balance and could use more extensive testing.
