I've not played that particular game but have played other games from Leading Edge. Assuming the game uses their system it is very crunchy with combat overly so. If you are at all familar with Phoenix Command, the combat system is a 'lite' version of this - which still makes it some of the most detailed/complex/trying to be realistic combat system I've experienced in a RPG.
So if you are into games which are rules heavy, very crunchy, go for it. Otherwise use the setting with your favourite rules system.
