Hah, yes we certainly do.
Not only it makes for quite a spectacle:
...rain, thunder in the distance, sad flute melody playing, field with hundreds of corpses, blood, mud, and fires burning here and there...
And here you come in and use this as a hay farm field
But this also has a huge impact on gameplay.
Just think about it - every two of your units which enemy kills gets them a unit of their own. As a result - we expect to see:
-fewer, but much more epic battles – players will be careful to only start a battle if they think they can win, or have no other choice.
-from time to time even 1 battle which will decided fate of the game. 3 players on 1 side and 3 on the other, 6,0000 units total after 10 minute build-up, come to face each other. Hell yeah
-and this renders any "unit spawning", or other mass production strategies useless.
Anyhow back to the topic of carrying your army and land. Yeah - what is the best way to grow the trees back? Would you rather see this done automatically, or have some tree-planting feature? Like a forester building?
