I dig it. Seriously. It's a great world, the adventures for it are AMAZING (more fond of the original Enemy Within campaign. The one put out most recently is a little too railroady, but still good.) The system is just the right amount of crunch v. flavor (of which it has both in vast quantities). My only issues with it are twofold, and one of them isn't really a legitimate grievance
IMHO.
1. they changed the magic system and the new one is seriously restrictive. As this $&#@s one of my characters ..... no bueno. However, the magic system is FAR and away better than the original, so overall net win.
2. I grow tired of Games Workshop constantly pulling the license and bringing it out of publication only to give it to a new group of people every few bloody years.
