I must admit I was one of those that were a bit sceptical when it came out, but people like yourself have 'enlightened' the rest of us (I hope)
It does seem like there has been a real effort to encapsulate key elements of warfare, something that is obviously lacking in the likes of 40K. The demoralizing effects of sustained heavy fire on an enemy can break them, even if they don't actually get killed, seems to be nicely modelled in the morale count down system for instance (the possibility of winning a game by suppressing fire only is just genius...)
As for scale, my vehicles are predominantly from S and S models and Westwind, so at the smaller end of the gaming/model scale, so I don't think I will suffer too much from the ranges given. Personally I think ranges are misleading half the time in games and shouldn't be on for the likes of tank guns and artillery that had effective ranges of thousands of meters so should be unlimited really, but we will see. We play mostly on 6'x4' boards anyways so sounds like it will all work out fine.
I've asked for it for my birthday, so we'll see how I get on!
