I had lots of fun trying this out! Despite getting some things wrong, I thought a couple of things were rather clever.
The assumption that figures on the battlefield are utilising terrain while not being directly behind cover was great. Being further than 2" from terrain leaves your men exposed, otherwise they're ducking in and out of crumbling walls etc.
I like Reaction systems. They can be tricky to keep track of when you start off, but I can see this getting easier... and the richness of game-play with this kind of system is well worth grappling with the concept!
I also like that you can play over a fairly small, crowded space and not be inhibited tactically (or bored!).
