I've played a couple of games now and I must admit I am not blown away. The main problem I am having is that they require lots of looking up of tables to determine outcomes, and those tables vary from race to race. The rulebook is fairly ameteurish in layout as while, which makes finding things difficult.
Maybe if I took the time to became more familiar with it it would become more fun to play, but right now I'm not overly enthusiastic.
I have read online lots of good stuff about it though, so maybe I'm missing something.
There is a review here:
