This is a very decent DLC for its price. Four new decks have a very distintic feel to them, the Brits have even got their own voicing, which is pretty cool (can't say about ze Germans, they all sound the same to me). Also the new game mode is kind of fun.
Of course there are some long standing issues with the game itself that have to be resolved ASAP and no amount of DLCs can help with that, but nonetheless it's a good purchase.
