I found I was very interested in the adversary decks. Bought both Imperial/Rebel and Scum and Villainy. Would have bought Citizens but it was sold out. Handy to have and to create random groups.

The spec decks on the other hand...nice idea but just too limited use for the $.

I have not found a need for the specialization decks.

The critical decks would be great if you could figure out a way to draw critical wounds and still be able to apply modifiers without wasting too much time.

The adversary decks are THE best auxiliary resource FFG provides. Absolutely worth it. I hope they release more.

I use the adversary deck - Citizens as only one that was available in the UK, all the rest out of stock and print on demand from FFG direct is way to pricy on shipping an duty/tax.

I have the critical hits decks too, and these are good but I wouldn't rush to get them. I would go for adversary decks every time.

As for the specialisation decks.. complete waste of space in my opinion. There are just too many decks and too many options and I would rather spend on source books.

I can see from their starting price that now on ebay and other sites, some are down to £3 a deck.. which just goes to show they really are not popular.

I wish they would do more ship decks and vehicle decks etc.. they would be handy.
