As with other Hearts of Iron DLCs, the price tag seems a bit unreasonable given the amount of content here. If you're a new player there is very little reason to pick this up, especially considering one of the best features (the historical Finish Focus Tree) has been added to the base game already. Sure, there are plenty of nice changes in here for veterans but a new player simply won't get much use out of them when they are already overwhelmed with different systems. For Hearts of Iron veterans though, this is one of the better DLCs overall (though still probably falling a bit short of the high water mark of No Step Back).

Hearts Of Iron IV: Arms Against Tyranny is a solid DLC. Adding a great slice of new content that more than just adds in a couple new focus trees and a crowbarred in mechanic like the previous one. The new focus trees are by and large great even if some feel a tad under cooked. However the arms trade system isn't as powerful as it should be. But the other additions almost make up for that.
