What a great game, I've been looking for a system like this for such a long time!
I've read and played almost all the fantasy/historical skirmish games out there and nothing has the subtlety, lightness and flexibility of this system. It's quite brilliant in many respects.
A little previous experience of wargames helps to get your head around the game concepts. The point sytem calculations for creating the stats for the figs is pretty straight forward to use (and it comes with a dozen army lists if you don't have the time to create your own or want to play it straight out of the box) but it's so worth it to be able to field any figure you have, even the most odd and dusty creature in the bottom of your miniatures box.
It's so flexible that I've heard that there are mods to turn it into modern or sci-fi without much dificulty. And I can see how easy that would be with such a smooth, intuitive and generic system, my mind is already running ahead and thinking how to adapt it myself.
Anyway, it gets my double thumbs up - I just hope they can add some other material for the game soon as I like their style!
