Good game but has many flaws/bugs;
1. When your armies are moving through neutral animals, instead of killing them, they'll walk through the neutral animals and stand there as the neutral animals ♥♥♥♥ your soldiers till they are half dead until your soldiers do anything about it.
2. You'll give your men orders to move across the map, they only move 1/16 of the way and stop, and you have to keep massing them orders and pay attention to them.
3. AI rushes you constantly, even before you have stable defenses (the game doesn't give you enough time to set up like other RTS games do).
If you want a good Cossacks game, stick to the original Cossacks: Back to War, it lets you build true defenses, less buggier and a little less micromanagement.
