I find the game barebones but a lot of fun. I wouldn't have gotten anything out of it playing on my own, but cooping the campaign with a friend is a lot of fun. The game mechanics are solid and the empire building is very fit for Warhammer.
EDIT: I'm actually looking forward to the pricey DLC.
Also, for those that care (hopefully you do), the game runs very, very well. Some people have had problems but it's nowhere the catastrophe Rome 2 was at launch, for example. My machine is lower tier but pulls it off quite perfectly; the lower graphics options, if not marvelously pretty, because they're lower graphics after all, they are still stylish and allows the game to run on comparably poor machines. Texture can be turned down significantly and it still looks better than eg Rome 1, Medieval 2.
However on snow maps with the shadows too poor, the ground looks really ugly. That's my only real complaint so far, but I just turned the shadow quality up, and the game runs just as well.
