Might be screen shots, but with really, really good physics engines/graphics card.
I just played the demo and it's quite fun.
I'm finding the Battle of Cyrenaica extremely annoying, because, no matter HOW strong I set my defenses, infantry walk right through my line and instantly kill the howitzer crews. Of course, they got their own cannons, which I can't get near because they have puppy guard Cavalry units protecting it, rendering any attack on those batteries useless. If my guys are in a Square, Cavalry don't attack; the second I go into a line of battle, they go start charging. Controlling the houses provided there didn't help, considering that the Cavalry units just up and walked right into it, killing all the guys in there, without any hope of escape.
