Played it and found it to be a let down tbh. There are LONG loading times (no its not my PC). A typical example would be during the campaign there are 2 loading screens before a battle and 2 loading screens after and each one takes about a minute each, I could understand if it was a huge scale game but you don't even have more than 300 units on the map (some maps are an exception) so it shouldn't take that long. Also I don't think much of the gameplay either since there isn't much strategy involved its just basically who ever has more or better units is going to win.
Being a Warhammer fan I'm also disapointed with the unit choice you are given since Gamesworkshop themselves have done most of the work creating and balancing the Armies and Races. The only thing I did find interesting was the Hero's, but that also soon became repetitive.
