I'll start by saying I love this game. I've been playing it on and off for four years now and have really enjoyed it. The things that draw me to this game are:
The setting is a wide sand box with enough detail to give it plenty of flavour and it is internally consistent. I also like the fact it is morally ambiguous and is not presented as "goodies & baddies".
The sand box approach means a GM can add their own detail while still keeping the flavour. As a GM I really enjoyed this.
The rules are simple, effective and reflect the setting. I found them reasonably intuitive and very adaptable. Combat is brutal and bloody.
The character creation system allows the creation of unique personalities with diverse skill sets, a definite strength of this game.
The down time options and character rewards provide a lot of alternatives for character advancement other than just "levelling up".
The core rulebook gives you everything you need for a good game and served us well until we got further supplements. If you add the Machines of War and The Eastern Bank supplements, then you have a plethora of options and depth. These three books have formed the foundation of my campaigns and served our group well.
I heartily recommend this system to anyone looking for a Sci-Fi/cyber-punk/espionage type game.
