Played a little, and really enjoyed it, the freedom you get in it is fantastic, combined with good game mechanics.
However the rules are not polished, and do require some moderation, with the costs of some units/weapons being a little 'iffy'. As long as you get players who play more for the enjoyment of the fluff and the game, rather than simply to win, then there isn't much of an issue, and we found it worked far better this way.
In terms of rules, we housed ruled it to be similar to NCE, (i believe it was designed for ORB) and agreed we could fiddle with the costs as long as we all agreed on them. Then there were no problems. ORB did suffer from ambiguity, and this carries over somewhat.
Overall, it is very enjoyable, even more so if you enjoy list writing, thanks to the sheer number of options available.
Enjoy!
