Mathias Well, if you said you had "playing cards", people would think you had a standard deck of 52 cards (four suits--two black, two red--from Ace to King) plus a few (usually two) Joker cards.
The UNO decks have cards in four colors, cards with the value 0 (but only half as many as you'd think!), no face cards (Jack, Queen, King), but cards w/actions and two types of "Wild" cards. All in all, over 100 cards, but not simply a double deck. The Wikipedia article tells of how the deck originally was (the one with which I used to play) and how more recent decks differ (more cards is one difference).
And, for hardcore "I want anything with Star Wars" collectors, this likely
is worth it.
