NOTE: I bought the Base Deck, Fantasy Deck, and Universal Instruction Cards, so this review is for each.
I debated whether to buy these or story dice, and I don't regret going with these. If you get them, I highly recommend buying the protective case as well. Also, you don't need a printed copy of the Universal Instruction Cards, but it's worth it if you like having the instructions with the decks.
Some things I like:
--They're printed on paper that feels like regular Poker cards, none are off-center, and the ink quality is very good.
--They have just about everything you need to get a story going on the fly.
--There is some overlap between the Base and Fantasy Decks, but the differences are enough to justify buying both.
--I received them a day earlier than expected.
Some things I would change:
--As others have noted, there are only a few Vices and Virtues. More would be better.
--The Universal Instruction Cards include one card that can be used as cover art, and I wish every set included one of these.
--The GMA Key card (included with the Universal Instruction Cards) is printed on both sides so that I had to keep flipping it over to learn how the cards work. It would be better if these were separated.
Overall, my gripes are minor, and these cards are easily worth the purchase.
